Information Retrieval System Explained: Types, Comparison & Components
Blogs
47654
An information retrieval (IR) system is a set of algorithms that facilitate the relevance of displayed documents to searched queries. In simple words, it works to sort and rank documents based on the queries of a user. There is uniformity with respect to the query and text in the document to enable document accessibility. Check out our data science free courses to get an edge over the competition. This also allows a matching function to be used effectively to rank a document formally using their Retrieval Status Value (RSV). The document contents are represented by a collection of descriptors, known as terms, that belong to a vocabulary V. An IR system also extracts feedback on the usability of the displayed results by tracking the user’s behaviour. You can also consider doing our Python Bootcamp course from upGrad to upskill your career. When we speak of search engines, we mean the likes of Google, Yahoo, and Bing among the general search engines. Other search engines include DBLP and Google Scholar.  In this article, we will look at the different types of IR models, the components involved, and the techniques used in Information Retrieval to understand the mechanism behind search engines displaying results.  Our learners also read: Free Python Course with Certification Types of Information Retrieval Model There are several information retrieval techniques and types that can help you with the process. An information retrieval comprises of the following four key elements: D − Document Representation. Q − Query Representation. F − A framework to match and establish a relationship between D and Q. R (q, di) − A ranking function that determines the similarity between the query and the document to display relevant information. Also read: Excel online course free! There are three types of Information Retrieval (IR) models: 1. Classical IR Model — It is designed upon basic mathematical concepts and is the most widely-used of IR models. Classic Information Retrieval models can be implemented with ease. Its examples include Vector-space, Boolean and Probabilistic IR models. In this system, the retrieval of information depends on documents containing the defined set of queries. There is no ranking or grading of any kind. The different classical IR models take Document Representation, Query representation, and Retrieval/Matching function into account in their modelling. This is one of the most used Information retrieval models. 2. Non-Classical IR Model — They differ from classic models in that they are built upon propositional logic. Examples of non-classical IR models include Information Logic, Situation Theory, and Interaction models. It is one of the types of information retrieval systems that is diametrically opposite to the conventional IR model.  Featured Program for you: Fullstack Development Bootcamp Course 3. Alternative IR Model — These take principles of classical IR model and enhance upon to create more functional models like the Cluster model, Alternative Set-Theoretic Models Fuzzy Set model, Latent Semantic Indexing (LSI) model, Alternative Algebraic Models Generalized Vector Space Model, etc. Let’s understand the most-adopted similarity-based classical IR models in further detail:  1. Boolean Model — This model required information to be translated into a Boolean expression and Boolean queries. The latter is used to determine the information needed to be able to provide the right match when the Boolean expression is found to be true. It uses Boolean operations AND, OR, NOT to create a combination of multiple terms based on what the user asks. This is one of the information retrieval models that is widely used.  2. Vector Space Model — This model takes documents and queries denoted as vectors and retrieves documents depending on how similar they are. This can result in two types of vectors which are then used to rank search results either  Binary in Boolean VSM. Weighted in Non-binary VSM. Check out our data science courses to upskill yourself. 3. Probability Distribution Model — In this model, the documents are considered as distributions of terms and queries are matched based on the similarity of these representations. This is made possible using entropy or by computing the probable utility of the document. They are if two types: Similarity-based Probability Distribution Model Expected-utility-based Probability Distribution Model 4. Probabilistic Models — The probabilistic model is rather simple and takes the probability ranking to display results. To put it simply, documents are ranked based on the probability of their relevance to a searched query. This is one of the most basic information retrieval techniques used.  Checkout: Data Science vs Data Analytics upGrad’s Exclusive Data Science Webinar for you – Transformation & Opportunities in Analytics & Insights document.createElement('video'); https://cdn.upgrad.com/blog/jai-kapoor.mp4   Components of Information Retrieval Model Here are the prerequisites for an IR model:  An automated or manually-operated indexing system used to index and search techniques and procedures. A collection of documents in any one of the following formats: text, image or multimedia. A set of queries that serve as the input to a system, via a human or machine. An evaluation metric to measure or evaluate a system’s effectiveness (for instance, precision and recall). For instance, to ensure how useful the information displayed to the user is.  If you draw and explain the IR system block diagram, you will come across different components. The various components of an Information Retrieval Model include:  Step 1 Acquisition The IR system sources documents and multimedia information from a variety of web resources. This data is compiled by web crawlers and is sent to database storage systems. Step 2 Representation The free-text terms are indexed, and the vocabulary is sorted, both using automated or manual procedures. For instance, a document abstract will contain a summary, meta description, bibliography, and details of the authors or co-authors. It is one of the components of the information retrieval system that involves summarizing and abstracting. Step 3 File Organization File organization is carried out in one of two methods, sequential or inverted. Sequential file organization involves data contained in the document. The Inverted file comprises a list of records, in a term by term manner. It is one of the components of information retrieval system that also involves the combination of the sequential and inverted methods.  Also visit upGrad’s Degree Counselling page for all undergraduate and postgraduate programs.

User queries can either be formal or informal statements highlighting what information is required. In IR systems, a query is not indicative of a single object in the database system. It could refer to several objects whichever match the query. However, their degrees of relevance may vary.  Explore our Popular Data Science Courses Executive Post Graduate Programme in Data Science from IIITB Professional Certificate Program in Data Science for Business Decision Making Master of Science in Data Science from University of Arizona Advanced Certificate Programme in Data Science from IIITB Professional Certificate Program in Data Science and Business Analytics from University of Maryland Data Science Courses Importance of Information Retrieval System What is information retrieval? Information is a vital resource for corporate operations, and it has to be managed effectively, just like any other vital resource. However, rapidly advancing technology is altering how even very tiny organizations manage crucial business data via information retrieval in AI. A business is held together by an information or records management system, which is most frequently electronic and created to acquire, analyze, retain, and retrieve information. After we understand what is information retrieval, we need to understand its importance.  Here are some reasons why Information Retrieval in AI is important in today’s world –  Productive and Efficient – It is unproductive and possibly expensive for small businesses and local companies to have an owner or employee spend time looking through piles of loose papers or attempting to find records that are missing or have been improperly filed. In addition to lowering the likelihood of information being misfiled, robust information storage and retrieval system that includes a strong indexing system also accelerates the storing and information extraction. This time-saving advantage results in increased office productivity and efficiency while lowering anxiety and stress. Regulatory Compliance – A privately owned corporation is exempt from the majority of federal and state compliance regulations, unlike a public company. Despite this, many people decide to voluntarily comply in order to increase accountability and the company’s reputation in public. Additionally, small-business owners are required to retain and maintain tax information so that it is easily available in the event of an audit. A well-organized system for information retrieval in Artificial Intelligence that adheres to compliance rules and tax record-keeping requirements greatly boosts a business owner’s confidence that the operation is entirely legal. Manual vs. Electronic – The value of electronic information retrieval in Artificial Intelligence is based on the fact that they demand less storage space and cost less in terms of both equipment and manpower. An ordered file system may be maintained using a manual approach, but it requires financial allotments for storage space, filing equipment, and administrative costs. Additionally, an electronic system may make it much simpler to implement and maintain internal controls intended to prevent fraud, as well as make sure the company is adhering to privacy regulations. Better Working Environment – Anyone passing through an office space may find it depressing to see important records and other material piled on top of file cabinets or in boxes close to desks. Not only does this lead to a tense and unsatisfactory work atmosphere, but if consumers witness this, it could give them a bad impression of the company. To understand how crucial it is for even a small firm to have efficient information storage and retrieval system. Difference Between Information Retrieval and Data Retrieval Data Retrieval systems directly retrieve data from database management systems like ODBMS by identifying keywords in the queries provided by users and matching them with the documents in the database.  Whereas the Information Retrieval system in DBMS is a set of algorithms or programs that involve storing, retrieving, evaluation of document and query representations, esp text-based, to display results based on similarity. S.No Information Retrieval Data Retrieval 1 Retrieves information based on the similarity between the query and the document. Retrieves data based on the keywords in the query entered by the user. 2 Small errors are tolerated and will likely go unnoticed. There is no room for errors since it results in complete system failure. 3 It is ambiguous and doesn’t have a defined structure. It has a defined structure with respect to semantics. 4 Does not provide a solution to the user of the database system. Provides solutions to the user of the database system. 5 Information Retrieval system produces approximate results Data Retrieval system produces exact results. 6 Displayed results are sorted by relevance  Displayed results are not sorted by relevance. 7 The IR model is probabilistic by nature. The Data Retrieval model is deterministic by nature. User Interaction with Information Retrieval System Now that you understand “what is information retrieval system,” let us understand the concept of user interaction with it.  The User Task It begins with the rise of a query from the information converted by the user. In an information retrieval system, conveying the semantics of the requested information is possible through a collection of words. Logical View of the Documents In the past, index terms or keywords were used for characterizing documents. Now, new computers can portray documents with a whole set of words. It can minimize the number of representative words. It is possible by deleting stop words like connectives and articles.  Understanding the Difference Between IRS and DBMS Let us discover the difference between IRS and DBMS here. Category DBMS IRS Data Modelling Facility A DBMS comes with an advanced Data Modeling Facility (DMF) that offers Data Definition Language and Data Manipulation Language.  The Data Modeling Facility is missing in an information retrieval system. In an IRS, data modeling is limited to the classification of objects.  Data Integrity Constraints The Data Definition Language of DBMS can easily define the data integrity constraints.  These validation mechanisms are less developed in an information retrieval system.  Semantics  A DBMS offers precise semantics.  The semantics offered by an information retrieval system is usually imprecise.  Data Format A DBMS comes with a structured data format.  An information retrieval system will have an unstructured data format.  Query Language The query language of a DBMS is artificial. The query language of an information retrieval system is extremely close to natural language.  Query Specification In a DBMS, query specification is always complete.  Query specification is incomplete in an IRS. Exploring the Past, Present, and Future of Information Retrieval After becoming aware of the information retrieval system definition, you should explore its past, present, and future: Early Developments: With the increasing need for gaining information, it also became necessary to build data structures for faster access. The index acts as a data structure for supporting fast information retrieval. For a long time, indexes involved manual categorization of hierarchies.  Information Retrieval in Libraries: The adoption of the IR system for information was popularized by libraries. In the first generation, it includes the automation of previous technologies. Therefore, the search was done according to the author’s name and title. In the second generation, searching is possible using the subject heading, keywords, and more. In the third generation, the search is possible using graphical interfaces, hypertext features, electronic forms, and more.  The Web and Digital Libraries: After learning the definition of an information retrieval system, you will realize that it is less expensive than various other sources of information. Therefore, it offers greater access to networks through digital communication. Moreover, it provides free access to publishing on a larger medium.  Conclusion This brings us to the end of the article. We hope you found the information helpful.

26 Must Read Shell Scripting Interview Questions & Answers [For Freshers & Experienced]
Blogs
12972
For those of you who use any of the major operating systems regularly, you will be interacting with one of the two most critical components of an operating system- a shell. So, what is Shell? It is both an interactive command language as well as a scripting language. Shell is the interface that connects the kernel and the user. A kernel, on the other hand, is an intermediary between the hardware and the operative system. The moment a user starts the terminal or logs in, you activate the shell. A Shell is a command-line interpreter or a complete environment designed to run commands, shell scripts, and programs. Once you feed commands into the shell, it will execute the program based on your input. When a user enters the command, the shell communicates it to the kernel. Upon execution, the output is displayed to the user. More than one shell can run simultaneously in a system, but only one kernel.  Shell scripting is a programming language used for automating and executing tasks on a Unix-like operating system. Shell scripts, as the name indicates, they are written in plain text formats that help in executing a diverse range of tasks such as: Sending emails Generating various reports Managing the files and repositories stored in the system Scheduling different tasks Running several programs automatically Essentially, it translates the input commands and converts them into a Kernel-compatible language. A Shell Script refers to a list of commands in a program run by the Unix Shell. The script includes comments defining the commands in order of their execution sequence.  Shell Scripting is an open-source computer program. It runs on the Unix/Linux shell and writes commands for the shell to execute. It doesn’t matter whether the sequence of commands is lengthy or repetitive; the program helps simplify it into a single script, making it easy to store and execute. A shell script may be one of the following- Bourne shell, C shell (CSH), Korn shell (KSH), and GNU Bourne-Again shell (BASH).  You may wonder, “Why should I concern myself with Shell Scripting?” The simple answer is- to increase efficiency through automation and remove mundane and repetitive tasks from your work schedule. The plain text file, or shell script, contains one or more command lines and can be executed rather than running manually. It reduces the manual effort that goes into programming. Additionally, it can help with system monitoring and taking routine backups. Shell Scripting assists in adding new functionalities to the shell, as well.  Thinking about opting for a career in Shell Scripting? Are you wondering what are some of the possible Unix Shell Scripting interview questions? If the introduction makes you want to know more about Shell Scripting, keep scrolling till the end – we’ve compiled a list of Shell Scripting interview questions and answers to help kickstart your learning process! If you want to learn more about data science, check out our data science courses.  Shell Scripting Interview Questions & Answers What are the advantages of Shell Scripting? The greatest benefits of Shell Scripting are: It allows you to create a custom operating system to best suit your requirements even if you are not an expert. It lets you design software applications based on the platform you’re using.  It is time-savvy as it helps automate system administration tasks. Compared to other programming languages, the shell script is faster and easier to code.  It can provide linkages between existing platforms. 2. What are Shell variables? Shell variables form the core part of a Shell program or script. The variables allow Shell to store and manipulate information within a Shell program. Shell variables are generally stored as string variables. 3. List the types of variables used in Shell Scripting. Usually, a Shell Script has two types of variables: System-defined variables – They are created by the OS(Linux) and are defined in capital letters. You can view them using the Set command.  User-defined variables – These are created and defined by system users. You can view the variable values using the Echo command. Our learners also read: Free online python course for beginners! How can you make a variable unchangeable? You can make a variable unchangeable using read-only. Let’s say you want the value of the variable ‘a’ to remain as five and keep it constant, so you use readonly like so: $ a=5 $ readonly a Name the different types of Shells. There are four core types of Shells, namely: Bourne Shell (sh) C Shell (csh) Korn Shell (ksh) Bourne Again Shell (bash) The two most important types of Shell in Linux are Bourne Shell and C Shell. Explain “Positional Parameters.” Positional parameters are variables defined by a Shell. They are used to pass information to the program by specifying arguments in the command line. How many Shells and Kernels are available in a UNIX environment? Typically, a UNIX environment has only one Kernel. However, there are multiple Shells available. Do you need a separate compiler to execute a Shell program?                           No, you don’t need a separate compiler to execute a Shell program. Since Shell itself is a command-line in the shell program and executes them. How do you modify file permissions in Shell Scripting? You can modify file permissions via umask. With the unmask (user file-creation mode mask) command, you can change the default permission settings of files that are newly created.   What does a “.” (dot) at the beginning of a file name indicate? A file name that starts with a “.” is a hidden file. Usually, when you try to list the files in a Shell, it lists all files except the hidden files. However, the hidden files are present in the directory. If you wish to view hidden files, you must run the Is command with the “–a” flag. upGrad’s Exclusive Data Science Webinar for you – document.createElement('video'); https://cdn.upgrad.com/blog/jai-kapoor.mp4 Explore our Popular Data Science Courses Executive Post Graduate Programme in Data Science from IIITB Professional Certificate Program in Data Science for Business Decision Making Master of Science in Data Science from University of Arizona Advanced Certificate Programme in Data Science from IIITB Professional Certificate Program in Data Science and Business Analytics from University of Maryland Data Science Courses Bash Scripting Interview Questions Below, there are potential unix interview questions that would help one to be well-informed and prepared in advance. Do you understand Linux? What is Linux? Linux is a type of open-source operating system based on the Linux Kernel, a computer program that is the core of computer operating systems, which enables managing a computer’s hardware and software. What is a Shell? A shell is an application that serves as the interface between the user and the Kernel. What do you mean by Shell Scripting? Shell scripting is written in a plain text format, a programming language that enables the user to automate and execute tasks on an operating system. What are the benefits of shell scripting? It is a lightweight and portable tool that can be used on any Unix-like operating system. It helps in automating and executing a wide variety of tasks It is easier to learn It enables a quick start and an interactive debugging Name different types of shells in shell scripting. C Shell, Bourne Again shell, and Korn shell are some different types of shell that can be used. What is a C shell? C shell or CSH shell is a shell scripting program that uses the C program shell syntax. It was created by Bill Joy in the 1970s in California, America. What are the limitations of shell scripting? Shell scripts are suitable for small tasks. It is difficult to manage and execute complex and big tasks that use multiple large data. It is prone to errors, a simple error may also delete the entire data  Some designs which are not apt or weak may prove to be quite expensive The portability of shell scripting is a huge task; it is not easy. What do you understand about a metacharacter? Meta character is a special character used in a program of a shell. It is used to match a similar pattern of characters in a file. For example, to list all the files in the program that begin with the letter ‘p’, use the ls p* command.

Myth Busted: Data Science doesn’t need Coding Business Intelligence vs Data Science: What are the differences? How to create a shortcut in Linux? You can create shortcuts in Linux via two links: Hard link – These links are linked to the inode of the file. They are always present in the same file system as the file. Even if you delete the original file, the hard link will remain unaffected.  Soft link – These links are linked to the file name. They may or may not reside on the same file system as the file. If you delete the original file, the soft link becomes inactive. 12. Name the different stages of a Linux process. Typically, a Linux process traverses through four phases: Waiting – In this stage, the Linux process has to wait for the requisite resource. Running – In this stage, the process gets executed.  Stopped – After successful execution, the Linux process stops. Zombie – In the final step, even though the process is no longer running, it remains active in the process table. Is there an alternative command for “echo?”  Yes, tput is an alternative for echo command. The tput command allows you to control how the output will be displayed on the screen. How many blocks does a file system contain? A file system has four blocks: Superblock – This block offers information on the state of a file system such as block size, block group size, usage information, empty/filled blocks and their respective counts, size & location of inode tables, etc. Bootblock – This block holds the bootstrap loader program that executes when a user boots the host machine.  Datablock – This block includes the file contents of the file system. Inode table – UNIX treats all elements as files, and all information related to files is stored in the inode table.  Must Read: Python Interview Questions Name the three modes of operation of vi editor. The three modes of operation are: Command mode – This mode treats and interprets any key pressed by a user as editor commands.  Insert mode – You can use this mode to insert a new text, edit an existing text, etc. Ex-command mode – A user can enter all commands at a command line. Define “Control Instructions.” How many types of control instructions are available in a Shell? Control instructions are commands that allow you to specify how the different instructions in a script should be executed. Thus, their primary purpose is to determine the flow of control in a Shell program. A Shell has four types of control instructions:  Sequence control instruction enforces the instructions to be executed in the same order in which they are in the program. Selection/decision control instruction that enables the computer to determine which instruction should be executed next. Repetition/loop control instruction that allows the computer to run a group of statements repetitively. Case-control instruction is used when you need to choose from a range of alternatives.

It is a system variable whose default value is space, tab, following by a new line. IFS denotes where a field or word ends in a line and where another begins.  Define “Metacharacters.” A Shell consists of metacharacters, which are special characters in a data field or program that offers information about other characters. For example, the “ls s*” command in a Shell lists all the files beginning with the character ‘s’. Differentiate between $* and $@. While $* treats a complete group of positional parameters as a single string, $@ treats each quoted argument as separate arguments. Also read: Python Developer Salary in India 21. Write the syntax of while loop in Shell Scripting.  In Shell Scripting, the while loop is used when you want to repeat its block of commands several times. The syntax for the “while” loop is: while [test condition] do commands… done How are break and continue commands different? The break command is used to escape out of a loop in execution. You can use the break command to exit from any loop command, including until and while loops. On the other hand, the continue command is used to exit the loop’s current iteration without leaving the complete loop. 23. Why do we use the Shebang line in Shell Scripting? The Shebang line is situated at the top of a Shell script/program. It informs the user about the location of the engine that executes the script. Here’s an example of a Shebang line: #!/bin/sh ct $1 Can you execute multiple scripts in a Shell? Yes, it is possible to execute multiple scripts in a Shell. The execution of multiple scripts allows you to call one script from another. To do so, you must mention the script’s name to be called when you wish to invoke it. Which command should you use to know how long a system has been running? You need to use the uptime command to know how long a system has been running. Here’s an example of the uptime command: u/user1/Shell_Scripts_2018> uptime Which command should you use to check the disk usage? You can use the following three commands to check the disk usage: df – It is used to check the free disk space. du – It is used to check the directory wise disk usage. dfspace – It checks the free disk space in megabytes (MB).  27. What do you mean by the Crontab? Crontab is short for cron table, where Cron is a job scheduler that executes tasks. Crontab is a list of commands you want to run on a schedule, along with the command you want to use to manage that list. 28. When should we not use Shell Scripting? We shouldn’t use Shell Scripting in these instances: If the task is highly complicated, such as writing a complete payroll processing solution, we shouldn’t use Shell Scripting. If the job requires a high level of productivity, we shouldn’t use Shell Scripting. If the job requires multiple software solutions, we shouldn’t use Shell Scripting. 29. How do you compare the strings in a Shell script? We use the test command to compare text strings. It compares text strings by comparing every character present in each string. Read: Data Engineer Interview Questions 30. What do you mean by a file system? A file system is a collection of files along with information related to those files. It controls how the data is retrieved and stored. Without file systems, data present in storage would only be a large body of data with no way of telling where one piece of data ends, and another begins. 31. Can you differentiate between single quotes and double quotes? Yes. We use single quotes where we don’t want to perform the variables’ evaluation to values. On the other hand, we use double quotes where we want to perform the variables’ evaluation to values. 32. What do you mean by GUI scripting? We use GUI to control a computer and its applications. Through GUI scripting, we can handle various applications, depending on the operating system. 33. What do you know about the Super Block in Shell scripting? The Super Block is a program that has a record of particular file systems. It contains characteristics including the block size, filled and empty blocks with their respective counts, the location and the size of the inode tables, usage information, the disk block map, etc. 34. What is the importance of the Shebang line? The Shebang line remains at the script’s top. It gives information about the location where the engine is, which executes the script. 35. Provide some of the most popular UNIX commands. Here are some of the most popular UNIX commands: cd – The cd command changes the directory to the user’s home directory when used as $ cd. You can use it to change the directory to test through $ cd test. ls – The ls command lists the files in the current directory when used as $ ls. You can use it to record files in the long format by using it as $ ls -lrt. rm – The rm command will delete the file named fileA when you use it as $ rm fileA. cat – This command would display the contents present in a file when you use it as $ cat filename. mv – The mv command can rename or move files. For example, the $ mv fileA fileB command would move files named fileA and fileB. date – The date command shows the present time and date. grep – The grep command can search for specific information in a file. For example, the $ grep Hello fileA command would search for the lines where the word ‘Hello’ is present. finger – The finger command shows information about the user. ps – The ps command shows the processes presently running on your machine. man – The man command shows the online help or manual about a specified command. For example, the $ ms rm command would display the online manual for the rm command. pwd – The pwd command shows the current working directory. wc – The wc command counts the number of characters, words, and lines present in a file. history – The history command shows the list of all the commands you used recently. gzip – The gzip command compresses the specified file. For example, the $ gzip fileA command would compress fileA and change it into fileA.gz. logname – The logname command would print the user’s log name. head – The head command shows the first lines present in the file. For example, the $ head -15 fileA command would display the first 15 lines of fileA. Additional Notes: This one is among the most crucial Shell scripting interview questions. We recommend preparing a more thorough list of UNIX commands as many versions of this question are asked in interviews. Must Read: Data Science Interview Questions 36. How is C Shell better than Bourne Shell? C Shell is better than Bourne Shell for the following reasons: C Shell lets you alias the commands. This means the user can give any desired name to a command. It is quite beneficial when the user has to use a lengthy command multiple times. Instead of typing the command’s long name numerous times, the user can type the assigned name. It saves a lot of time and energy, making the process much more efficient. C Shell has a command history feature, where C Shell remembers all the previously used commands. You can use this feature to avoid typing the same command multiple times. It enhances efficiency substantially. Due to the above two reasons, using C Shell is much more advantageous than Bourne Shell. 37. What is it essential to write Shell Scripts? Shell scripting has many benefits that make it crucial. It takes input from users, files it, and displays it on the screen. Moreover, it allows you to make your own commands and automate simple daily tasks. You can use Shell scripting to automate system administration tasks also. Shell scripting makes your processes more efficient by saving you a lot of energy and time. Due to this, it is quite essential and widely used. 38. What are some disadvantages of Shell Scripting? Just as there are several advantages of Shell Scripting, there are also some disadvantages of the program. Shell Script interview questions may ask you to count some of them. They are as follows: Shell scripts are slow in execution. Errors in the shell script may prove to be very costly. Compatibility problems may arise across different problems.  Complex scripts may be difficult to execute. 39. What is Shell Scripting? One of the most basic Shell Script interview questions is what is shell scripting? Simply put, Shell Scripting is an open-source computer program run by Unix/Linus shell to create plain text files that store and execute command lines. It removes the need to code and run repetitive commands manually each time. 40. What is Shell? One of the most unavoidable Unix Shell Scripting interview questions will require you to define Shell. A Shell is an intermediary connecting the kernel and the user. It communicates with the kernel when a user enters a command for execution. Ultimately, the output is displayed to the user.  Conclusion Shell Scripting is a time saver for programs. If you want to remove mundane and repetitive tasks from your workload, Shell Scripting can help you tremendously. You don’t even need to be an expert. We hope these 26 Shell Scripting interview questions and answers help you break the ice on Shell Scripting and prepare for your next interview!

4 Types of Data: Nominal, Ordinal, Discrete, Continuous
Blogs
284094
Summary: In this Article, you will learn about 4 Types of Data Qualitative Data Type Nominal Ordinal Quantitative Data Type Discrete Continuous Read more to know each in detail. Introduction Data science is all about experimenting with raw or structured data. Data is the fuel that can drive a business to the right path or at least provide actionable insights that can help strategize current campaigns, easily organize the launch of new products, or try out different experiments. All these things have one common driving component and this is Data. We are entering into the digital era where we produce a lot of Data. For instance, a company like Flipkart produces more than 2TB of data on daily basis.  In simple terms, data is a systematic record of digital information retrieved from digital interactions as facts and figures. Types of statistical data work as an insight for future predictions and improving pre-existing services. The continuous data flow has helped millions of organizations to attain growth with fact-backed decisions. Data is a vast record of information segmented into various categories to acquire different types, quality, and characteristics of data, and these categories are called data types. When this Data has so much importance in our life then it becomes important to properly store and process this without any error. When dealing with datasets, the category of data plays an important role to determine which preprocessing strategy would work for a particular set to get the right results or which type of statistical analysis should be applied for the best results. Let’s dive into some of the commonly used categories of data. Qualitative Data Type Qualitative or Categorical Data describes the object under consideration using a finite set of discrete classes. It means that this type of data can’t be counted or measured easily using numbers and therefore divided into categories. The gender of a person (male, female, or others) is a good example of this data type. These are usually extracted from audio, images, or text medium. Another example can be of a smartphone brand that provides information about the current rating, the color of the phone, category of the phone, and so on. All this information can be categorized as Qualitative data. There are two subcategories under this: Must read: Data structures and algorithms free course! Nominal These are the set of values that don’t possess a natural ordering. Let’s understand this with some examples. The color of a smartphone can be considered as a nominal data type as we can’t compare one color with others. It is not possible to state that ‘Red’ is greater than ‘Blue’. The gender of a person is another one where we can’t differentiate between male, female, or others. Mobile phone categories whether it is midrange, budget segment, or premium smartphone is also nominal data type. Nominal data types in statistics are not quantifiable and cannot be measured through numerical units. Nominal types of statistical data are valuable while conducting qualitative research as it extends freedom of opinion to subjects. Read: Career in Data Science Ordinal These types of values have a natural ordering while maintaining their class of values. If we consider the size of a clothing brand then we can easily sort them according to their name tag in the order of small < medium < large. The grading system while marking candidates in a test can also be considered as an ordinal data type where A+ is definitely better than B grade.  These categories help us deciding which encoding strategy can be applied to which type of data. Data encoding for Qualitative data is important because machine learning models can’t handle these values directly and needed to be converted to numerical types as the models are mathematical in nature. For nominal data type where there is no comparison among the categories, one-hot encoding can be applied which is similar to binary coding considering there are in less number and for the ordinal data type, label encoding can be applied which is a form of integer encoding. Difference Between Nominal and Ordinal Data Aspect Nominal Data Ordinal Data Definition Categories data into distinct classes or categories without any inherent order or ranking. Categories data into ordered or ranked categories with meaningful differences between them. Examples Colors, gender, types of animals Education levels, customer satisfaction ratings Mathematical Operations No meaningful mathematical operations can be performed (e.g., averaging categories). Limited mathematical operations can be performed, such as determining the mode or median. Order/ Ranking No natural or meaningful order exists. Categories have a specific order or ranking, but the magnitude of differences between ranks may not be uniform. Central Tendency Mode (most frequent category) Mode, median (middle category), but mean is not typically used due to lack of uniform interval between ranks. Example Use Case Classifying objects, grouping data Rating scales, survey responses, educational levels Quantitative Data Type This data type tries to quantify things and it does by considering numerical values that make it countable in nature. The price of a smartphone, discount offered, number of ratings on a product, the frequency of processor of a smartphone, or ram of that particular phone, all these things fall under the category of Quantitative data types. Also read: Learn python online free! The key thing is that there can be an infinite number of values a feature can take. For instance, the price of a smartphone can vary from x amount to any value and it can be further broken down based on fractional values. The two subcategories which describe them clearly are: Discrete The numerical values which fall under are integers or whole numbers are placed under this category. The number of speakers in the phone, cameras, cores in the processor, the number of sims supported all these are some of the examples of the discrete data type. Discrete data types in statistics cannot be measured – it can only be counted as the objects included in discrete data have a fixed value. The value can be represented in decimal, but it has to be whole. Discrete data is often identified through charts, including bar charts, pie charts, and tally charts. Our learners also read: Excel online course free! upGrad’s Exclusive Data Science Webinar for you – Transformation & Opportunities in Analytics & Insights document.createElement('video'); https://cdn.upgrad.com/blog/jai-kapoor.mp4 Continuous  The fractional numbers are considered as continuous values. These can take the form of the operating frequency of the processors, the android version of the phone, wifi frequency, temperature of the cores, and so on.  Unlike discrete data types of data in research, with a whole and fixed value, continuous data can break down into smaller pieces and can take any value. For example, volatile values such as temperature and the weight of a human can be included in the continuous value. Continuous types of statistical data are represented using a graph that easily reflects value fluctuation by the highs and lows of the line through a certain period of time.  Difference between Discrete Data and Continous Data Aspect Discrete Data Continuous Data Definition Consists of distinct, separate values. It can take any value within a given range. Examples Number of students in a class, coin toss outcomes (1, 2, 3), customer count. Height, weight, temperature, time. Nature Usually involves whole numbers or counts. Involves any value along a continuous spectrum. Gaps in values Gaps between values are common and meaningful. Values can be infinitely divided without gaps. Measurement Often measured using integers. Measured with decimal numbers or fractions. Graphical representation Typically represented with bar charts or histograms. Represented with line graphs or smooth curves. Mathematical Operations Typically involves counting or summation. Involves arithmetic operations, including fractions and decimals. Probability Distribution Typically represented using probability mass functions Typically represented using probability density functions. Example Use Case Counting occurrences, tracking integers. Measuring quantities and analyzing measurements.

This type of data in statistics helps run market analysis through genuine figures and create value out of service by implementing useful information. Qualitative types of data in statistics can drastically affect customer satisfaction if applied smartly. On the other hand, the Quantitative data types of statistical data work with numerical values that can be measured, answering questions such as ‘how much’, ‘how many’, or ‘how many times’. Quantitative data types in statistics contain a precise numerical value. Therefore, they can help organizations use these figures to gauge improved and faulty figures and predict future trends. Must Read: Data Scientist Salary in India Can Ordinal and Discrete type overlap? If you pay attention to this, you can give numbering to the ordinal classes, and then it should be called discrete type or ordinal? The truth is that it is still ordinal. The reason for this is that even if the numbering is done, it doesn’t convey the actual distances between the classes. For instance, consider the grading system of a test. The respective grades can be A, B, C, D, E, and if we number them from starting then it would be 1,2,3,4,5. Now according to the numerical differences, the distance between E grade and D grade is the same as the distance between the D and C grade which is not very accurate as we all know that C grade is still acceptable as compared to E grade but the mid difference declares them as equal. You can also apply the same technique to a survey form where user experience is recorded on a scale of very poor to very good. The differences between various classes are not clear therefore can’t be quantified directly.  Top Data Science Skills to Learn Top Data Science Skills to Learn 1 Data Analysis Course Inferential Statistics Courses 2 Hypothesis Testing Programs Logistic Regression Courses 3 Linear Regression Courses Linear Algebra for Analysis Different Tests We have discussed all the major classifications of Data. This is important because now we can prioritize the tests to be performed on different categories. Now it makes sense to plot a histogram or frequency plot for quantitative data and a pie chart and bar plot for qualitative data. Regression analysis, where the relationship between one dependent and two or more independent variables is analyzed is possible only for quantitative data. ANOVA test (Analysis of variance) test is applicable only on qualitative variables though you can apply two-way ANOVA test which uses one measurement variable and two nominal variables. In this way, you can apply the Chi-square test on qualitative data to discover relationships between categorical variables. Why Are Data Types Important in Statistics?  Data types play a crucial role in statistics for several reasons: 1. Data Understanding Data types provide information about the nature of the variables and the kind of values they can take, aiding in understanding the dataset. 2. Analysis Selection Different data types require different analysis techniques. Choosing the appropriate analysis method depends on the data types involved. 3. Statistical Tests The choice of statistical tests depends on the data types of variables. Parametric tests are used for continuous data, while non-parametric tests are suitable for categorical or ordinal data. 4. Data Treatment Understanding data types helps decide how to effectively handle missing values, outliers, and other data anomalies. 5. Visualization Data types determine the visualizations most appropriate for conveying insights, such as bar charts for categorical data and histograms for continuous data. 6. Data Transformation Data types influence the need for data transformation, such as normalizing or standardizing continuous variables for certain analyses. 7. Model Building In machine learning and regression analysis, the type of dependent and independent variables affects the choice of algorithms and the model’s assumptions. 8. Interpretation Data types impact how results are interpreted. The meaning of statistical measures like mean, median, and mode varies based on whether the data is continuous, discrete, or categorical. 9. Accuracy and Validity Misidentifying data types can lead to incorrect analyses, invalid conclusions, and inaccurate predictions. 10. Data Integration Understanding data types ensures consistency and compatibility between datasets when combining data from different sources. 11. Data Privacy and Security Sensitivity to data types helps preserve data privacy by ensuring that the appropriate anonymization techniques are applied based on the data’s nature. 12. Reporting and Communication Accurate identification of data types ensures that findings are communicated clearly and accurately to stakeholders and decision-makers. 13. Efficient Storage Understanding data types helps in efficient data storage and retrieval, optimizing database performance. 14. Resource Allocation Data types affect memory and processing requirements. The efficient allocation of resources depends on accurate knowledge of data types.

A sequence classification problem deals with the prediction of sequential patterns in data sets. It discovers the underlying order in the database based on specific labels. In doing so, it applies the simple mathematical tool of partial orders. However, you would require a better representation to achieve more accurate, concise, and scalable classification. And a sequence classification technique with a behavioral constraint template can address this need. With the iBCM project, you can delve into the field of sequence categorization. Using behavioral constraint templates, this venture predicts sequential patterns inside datasets. This method employs mathematical tools such as partial orders to reveal underlying data patterns in an accurate and simple manner. Beyond traditional sequence mining, iBCM finds a wide range of patterns, making it a good starting point for inexperienced data miners. The interesting Behavioral Constraint Miner (iBCM) project can express a variety of patterns over a sequence, such as simple occurrence, looping, and position-based behavior. It can also mine negative information, i.e., the absence of a particular behavior. So, the iBCM approach goes much beyond the typical sequence mining representations and is a perfect starting point for those looking for data mining projects for students. 2. GERF: Group Event Recommendation Framework This is one of the simple data mining projects yet an exciting one. It is an intelligent solution for recommending social events, such as exhibitions, book launches, concerts, etc. A majority of the research focuses on suggesting upcoming attractions to individuals. So, a Group Event Recommendation Framework (GERF) was developed to propose events to a group of users. GERF addresses group social event recommendations by utilizing learning-to-rank algorithms for reliable choices. This project provides efficient event recommendations for a varied user population by extracting group preferences and environmental impacts, with applications ranging from exhibitions to travel services. This model uses a learning-to-rank algorithm to extract group preferences and can incorporate additional contextual influences with ease, accuracy, and time-efficiency. Learning to rank, also known as machine-learned ranking (MLR), is the process of building ranking models for systems needing information retrieval using machine learning techniques such as supervised learning, semi-supervised learning, and reinforcement learning. The objects used for training are organized into lists, with the relative order between the lists being partially described. In most cases, a number or ordinal score is assigned to each item, or a binary judgment (such as “relevant” for true values(binary 1) or “not relevant” for false values(binary 0)) is made. The objective of the ranking model is to apply the same logic used to rank the training data to the rating of fresh, unknown lists. Also, it can be conveniently applied to other group recommendation scenarios like location-based travel services.  Explore our Popular Data Science Courses Executive Post Graduate Programme in Data Science from IIITB Professional Certificate Program in Data Science for Business Decision Making Master of Science in Data Science from University of Arizona Advanced Certificate Programme in Data Science from IIITB Professional Certificate Program in Data Science and Business Analytics from University of Maryland Data Science Courses upGrad’s Exclusive Data Science Webinar for you – The Future of Consumer Data in an Open Data Economy document.createElement('video'); https://cdn.upgrad.com/blog/sashi-edupuganti.mp4 3. Efficient similarity search for dynamic data streams Online applications use similarity search systems for tasks like pattern recognition, recommendations, plagiarism detection, etc. Typically, the algorithm answers nearest-neighbor queries with the Location-Sensitive Hashing or LSH approach, a min-hashing related method. It can be implemented in several computational models with large data sets, including MapReduce architecture and streaming. Mentioning data mining projects can help your resume look much more interesting than others. For a variety of functions, online apps rely on similarity search engines. This research focuses on effective similarity search strategies for dynamic data streams, with a special emphasis on scalability in huge datasets. Its novel features, such as the use of the Jaccard index as a similarity measure and estimating techniques based on sketching, improve accuracy in pattern recognition and recommendation tasks. Dynamic data streams, however, require scalable LSH-based filtering and design. To this end, the efficient similarity search project outperforms previous algorithms. Here are some of its main features: Relies on the Jaccard index as a similarity measure Suggests a nearest-neighbor data structure feasible for dynamic data streams Proposes a sketching algorithm for similarity estimation  4. Frequent pattern mining on uncertain graphs Application domains like bioinformatics, social networks, and privacy enforcement often encounter uncertainty due to the presence of interrelated, real-life data archives. This uncertainty permeates the graph data as well. Frequent pattern mining on uncertain graphs is critical in settings requiring uncertain data, such as bioinformatics and social networks. This project addresses the issue of transitive interactions with uncertain graph data. It efficiently manages real-world data archives with increased performance by utilizing enumeration-evaluation methods and approximation techniques. This problem calls for innovative data mining projects that can catch the transitive interactions between graph nodes. This beginner-level data mining projects will help build a strong foundation for fundamental programming concepts. One such technique is the frequent subgraph and pattern mining on a single uncertain graph. The solution is presented in the following format: An enumeration-evaluation algorithm to support computation under probabilistic semantics An approximation algorithm to enable efficient problem-solving Computation sharing techniques to drive mining performance Integration of check-point based and pruning approaches to extend the algorithm to expected semantics 5. Cleaning data with forbidden itemsets or FBIs Data cleaning methods typically involve taking away data errors and systematically fixing the issue by specifying constraints (illegal values, domain restrictions, logical rules, etc.)   Data cleansing frequently entails defining limitations to correct inaccuracies. The FBI’s effort introduces a fixing method based on banned itemset, finding constraints in dirty data automatically and improving error detection precision. Empirical evaluations establish the mechanism’s trustworthiness and dependability, which is critical in the big data scenario. In the real-life big data universe, we are inundated with dirty data that comes without any known constraints. In such a scenario, the algorithm automatically discovers constraints on the dirty data and further uses them to identify and repair errors. But when this discovery algorithm runs on the repaired data again, it introduces new constraint violations, rendering the data erroneous. This is one of the excellent data mining projects for beginners. Hence, a repairing method based on forbidden itemsets (FBIs) was devised to record unlikely co-occurrences of values and detect errors with more precision. And empirical evaluations establish the credibility and reliability of this mechanism.  Top Data Science Skills to Learn Top Data Science Skills to Learn 1 Data Analysis Course Inferential Statistics Courses 2 Hypothesis Testing Programs Logistic Regression Courses 3 Linear Regression Courses Linear Algebra for Analysis 6.

Sentimental analysis and opinion mining for mobile networks This project concerns post-publishing applications where a registered user can share text posts or images and also leave comments on posts. Under the prevailing system, users have to go through all the comments manually to filter out verified comments, positive comments, negative remarks, and so on. With the sentiment analysis and opinion mining system, users can check the status of their post without dedicating much time and effort. It provides an opinion on the comments made on a post and also gives the option to view a graph.  10. Mining the k most frequent negative patterns via learning In behavior informatics, the negative sequential patterns (NSPs) can be more revealing than the positive sequential patterns (PSPs). For instance, in a disease or illness-related study, data on missing a medical treatment can be more useful than data on attending a medical procedure. But to the present day, NSP mining is still at a nascent stage. And the ‘Topk-NSP+’ algorithm presents a reliable solution for overcoming the obstacles in the current mining landscape. This is one of the trending data mining and this is how the project proposes the algorithm: Mining the top-k PSPs with the existing method Mining the to-k NSPs from these PSPs by using an idea similar to the top-k PSPs mining  Employing three optimization strategies to select useful NSPs and reduce computational costs Also try: Machine Learning Project Ideas for Beginners 11. Automated personality classification project The automatic system analyzes the characteristics and behaviors of participants. And after observing the past patterns of data classification, it predicts a personality type and stores its own patterns in a dataset. This project idea can be summarized as follows: Store personality-related data in a database Collect associated characteristics for each user Extract relevant features from the text entered by the participant Examine and display the personality traits  Interlink personality and user behavior (There can be varying degrees of behavior for a particular personality type) Such models are commonplace in career guidance services where a student’s personality is matched with suitable career paths. This can be an interesting and useful data mining projects. 12. Social-Aware social influence modeling This is one of the most popular data mining mini projects. This project deals with big social data and leverages deep learning for sequential modeling of user interests. The stepwise process is described below: A preliminary analysis of two real datasets (Yelp and Epinions) Discovery of statistically sequential actions of users and their social circles, including temporal autocorrelation and social influence on decision-making Presentation of a novel deep learning model called Social-Aware Long Short-Term Memory (SA-LSTM), which can predict the type of items or Points of Interest that a particular user will buy or visit next. Long short-term memory, often known as LSTM, is a kind of neural network that is used in the domains of deep learning and artificial intelligence. LSTM neural networks have feedback connections, in contrast to more traditional feedforward neural networks so that they can change the training parameters or hyperparameters to be more precise, with each epoch. LSTM is a kind of recurrent neural network, commonly known as an RNN, which is capable of processing, not just individual data points but also complete data sequences. Experimental results reveal that the structure of this proposed solution enables higher prediction accuracy as compared to other baseline methods. This is one of the data mining mini projects that will definitely help you get some real-world exposure. 13. Predicting consumption patterns with a mixture approach Individuals consume a large selection of items in the digital world today. For example, while making purchases online, listening to music, using online navigation, or exploring virtual environments. Applications in these contexts employ predictive modeling techniques to recommend new items to users. However, in many situations, we want to know the additional details of previously-consumed items and past user behavior. And this is where the baseline approach of matrix factorization-based prediction falls short. This is one of the creative data mining projects.  A mixture model with repeated and novel events offers a suitable alternative for such problems. It aims to deliver accurate consumption predictions by balancing individual preferences in terms of exploration and exploitation. Also, it is one of those data mining project topics that include an experimental analysis using real-world datasets. The study’s results show that the new approach works efficiently across different settings, from social media and music listening to location-based data.  14. GMC: Graph-based Multi-view Clustering  The existing clustering methods for multi-view data require an extra step to produce the final cluster as they do not pay much attention to the weights of different views. Moreover, they function on fixed graph similarity matrices of all views. And this is the perfect idea for your next data mining project as this can also be considered as a graph mining projects. A novel Graph-based Multi-view Clustering (GMC) can tackle this issue and deliver better results than the previous alternatives. It is a fusion technique that weights data graph matrices for all views and derives a unified matrix, directly generating the final clusters. Other features of the graph mining projects include: Partition of data points into the desired number of clusters without using a tuning parameter. For this, a rank constraint is imposed on the Laplacian matrix of the unified matrix. Optimization of the objective function with an iterative optimization algorithm  15. ITS: Intelligent Transportation System A multi-purpose traffic solution generally aims to ensure the following aspects: Transport service’s efficiency Transport safety Reduction in traffic congestion Forecast of potential passengers Adequate allocation of resources Consider a project that uses the above system to optimize the process of bus scheduling in a city. ITS is one of the interesting data mining projects for beginners. You can take the past three years’ data from a renowned bus service company, and apply uni-variate multi-linear regression to conduct passengers’ forecasts. Further, you can calculate the minimum number of buses required for optimization in a Generic Algorithm. Finally, you validate your results using statistical techniques like mean absolute percentage error (MAPE) and mean absolute deviation (MAD). Mean Absolute Percentage Error(MAPE): The accuracy of a forecasting system may be quantified by calculating the mean absolute percentage error (MAPE). Measured as a percentage, it is derived by taking the sum of the absolute values of the errors across all time periods and dividing by the real values to provide a reading on how close the estimate is to the true value. The most popular way to quantify forecast errors is via the use of the mean absolute percentage error (MAPE), perhaps because the variable’s units are already in percentage form. A lack of extremes in the data is necessary for optimal performance (and no zeros). In regression analysis and model assessment, it is frequently used as a loss function. Mean Absolute Deviation(MAD): It measures how far each data point is from the dataset’s mean value. It helps us get a sense of the data’s overall dispersion. To find out the MAD for a data set, we must first calculate the mean and then the distance of each data point from the mean using MPD(Mean positive distances) which would yield the absolute deviation. This absolute deviation is the measure of this gap between the mean and each data point. Now, we take the total of all these deviations, add it and then divide it by the total number of data points in the data set. Also read: Data Science Project Ideas 16. TourSense for city tourism City-scale transport data about buses, subways, etc. could also be used for tourist identification and preference analytics. But relying on traditional data sources, such as surveys and social media, can result in inadequate coverage and information delay. The TourSense project demonstrates how to override such shortcomings and provide more valuable insights. This tool would be useful for a wide range of stakeholders, from transport operators and tour agencies to tourists themselves. This is one of the excellent data mining projects for beginners. Here are the main steps involved in its design:  A graph-based iterative propagation learning algorithm to identify tourists from other public commuters A tourist preference analytics model (utilizing the tourists’ trace data) to learn and predict their next tour An interactive UI to serve easy information access from the analytics Data Mining Projects: Conclusion In this article, we have covered 16 data mining projects. If you wish to improve your data mining skills, you need to get your hands on these data mining projects. Dive into Data Science involves more than just academic understanding; it also necessitates practical experience. These data mining project ideas are designed for novices, with options to investigate sequence classification, group suggestions, similarity search, graph mining, and data cleaning.

Question 6. List the advantages NumPy Arrays have over (nested) Python lists? Python’s lists, even though hugely efficient containers capable of a number of functions, have several limitations when compared to NumPy arrays. It is not possible to perform vectorised operations which includes element-wise addition and multiplication.  They also require that Python store the type information of every element since they support objects of different types. This means a type dispatching code must be executed each time an operation on an element is done. Also, each iteration would have to undergo type checks and require Python API bookkeeping resulting in very few operations being carried by C loops.  This makes for one of the commonly asked numpy questions, where the advantages are required to enlist. Another advantage could be the less memory space that is utilized to store the data which helps in further optimization of the code. Scientific computing and array-oriented computing are more aligned advantages of NumPy. Question 7: List the steps to create a 1D array and 2D array A one-dimensional array is created as follows:  num=[1,2,3] num = np.array(num) print(“1d array : “,num)  A two-dimensional array is created as follows:  num2=[[1,2,3],[4,5,6]] num2 = np.array(num2) print(“\n2d array : “,num2) A 1-D array stands for a one-dimensional array that creates the array in one dimension. Whereas the 2D arrays have a collection of rows and columns. Check out: Data Science Interview Questions Question 8: How do you create a 3D array?

Use the following sequence of codes to identify the datatype of a NumPy array.  print(‘\n data type num 1 ‘,num.dtype) print(‘\n data type num 2 ‘,num2.dtype) print(‘\n data type num 3 ‘,num3.dtype) Our learners also read: Free Online Python Course for Beginners Question 11. What is the procedure to count the number of times a given value appears in an array of integers? You can count the number of times a given value appears using the bincount() function. It should be noted that the bincount() function accepts positive integers or boolean expressions as its argument. Negative integers cannot be used.  Use NumPy.bincount(). The resulting array is >>> arr = NumPy.array([0, 5, 4, 0, 4, 4, 3, 0, 0, 5, 2, 1, 1, 9]) >> NumPy.bincount(arr)   Must read: Data structures and algorithm free! Question 12. How do you check for an empty (zero Element) array? If the variable is an array, you can check for an empty array by using the size attribute. However, it is possible that the variable is a list or a sequence type, in that case, you can use len(). The preferable way to check for a zero element is the size attribute. This is because:  >>> a = NumPy.zeros((1,0)) >>> a.size 0 whereas >>> len(a) 1 Question 13: What is the procedure to find the indices of an array on NumPy where some condition is true? You may use the function numpy.nonzero() to find the indices or an array. You can also use the nonzero() method to do so.  In the following program, we will take an array a, where the condition is a > 3. It returns a boolean array. We know False on Python and NumPy is denoted as 0. Therefore, np.nonzero(a > 3) will return the indices of the array a where the condition is True.  >>> import numpy as np >>> a = np.array([[1,2,3],[4,5,6],[7,8,9]]) >>> a > 3 array([[False, False, False],        [ True,  True,  True],        [ True,  True,  True]], dtype=bool) >>> np.nonzero(a > 3) (array([1, 1, 1, 2, 2, 2]), array([0, 1, 2, 0, 1, 2])) You can also call the nonzero() method of the boolean array. >>> (a > 3).nonzero() (array([1, 1, 1, 2, 2, 2]), array([0, 1, 2, 0, 1, 2])) Read: Dataframe in Apache PySpark: Comprehensive Tutorial Question 14: Shown below is the input NumPy array.
