Data Science projects in R

1. Sentiment Analysis project

Sentiment analysis extracts opinions that bear different scores, like negative, positive, or neutral. You can use sentiment analysis to determine your sentences’ or opinion’s nature in text. It is a kind of classification where the data is categorized into various classes like positive, negative, sad, happy, etc. This concept is used in many data science projects for final year.

Customer satisfaction is one of the most crucial goals of almost every company and brand now. The best way to create a fanbase of loyal and satisfied customers is to get into their psyche – understand their likes and dislikes, identify their preference patterns, and most importantly, their needs. Sentiment Analysis is the tool that most companies use to understand the attitude of their target audience toward their products/services.

As the name suggests, Sentiment Analysis analyzes the words to identify the underlying emotions of the people expressing them. By analyzing the words, the Sentiment Analysis tool categorizes them under two binaries – as positive, negative, and neutral. In this project, you’ll use the ‘janeaustenR’ dataset/package. Other tools used in the project include general-purpose lexicons such as AFINN, Bing, and Loughran. Also, you will use a word cloud to display the outcomes. 

Usually, the Sentiment analysis uses the following main packages:

  • tm: It is used for text mining operations like discarding special characters, numbers, stop words, and punctuations.
  • word cloud: It is used for creating the word cloud plot.
  • syuzhet: It is used for emotion classification and sentiment scores.
  • ggplot2: It is used for plotting graphs.

2. Uber Data Analysis project

Uber is a data-driven brand through and through. The company mines and leverages user data to craft the best-suited cab solutions for its customers. While Uber is invested in making data-driven decisions, it also leverages a combination of advanced data analytics and predictive analytics to design its marketing strategies, promotional offers, and pricing policies. 

In this project, you’ll design a data analysis system using the ggplot2 library to gain insights from user data and to generate nearly accurate predictions of customers who will avail Uber trips and rides. The system will use R programming and the ggplot2 library to analyze different customer parameters like the number of trips made in a day, the daily trip hours of repeat customers, the number of trips during a particular month, etc.

By visualizing these data points, the system can figure out the average number of passengers that avail Uber trips in a day, the peak hours when there’s maximum traffic in the app, the days with the highest number of trips in a month, and so on. 

This project lets you understand an organization’s complex data visualization. It is created using the ‘R’ programming language.

Its first step involves importing the big data sets from the Internet to a programming language platform like ggthemes, ggplot2, dplyr, lubridate, DT, tidlyr, and scales. You must go through how these libraries are implemented in the project.

The developer must know about the fundamentals of the R language. Data visualization simplifies understanding the databases’ core values. The data science field is quite interesting, and this project justifies it. Moreover, this project is useful not just for Uber but also for various apps that need to access information from their massive databases. You can consider Uber projects or related data science projects for final year if you have a solid foundation of data science fundamentals.

This project uses the following:

  • Ggplot2: It is broadly used to create appealing visualization plots.
  • Ggthemes: It is a library for several themes from which the user can attain the anticipated scale for their database.
  • Lubridate: It includes time frames, and it must be mentioned in separate time categories.
  • DT: It helps you in developing an interface between Javascript and the program.
  • Tidyr: This function classifies the huge data into several rows and columns. So you can manipulate it easily.

3. Credit Card Fraud Detection project

Of late, credit card frauds have skyrocketed. In fact, it is one of the most prevalent menaces of the BFSI sector. The idea behind this R project is to develop a classifier that can efficiently detect credit card fraudulent transactions. You will learn how to execute machine learning algorithms to carry out classification after the end of this project.

The dataset for the project will be credit card transaction dataset containing a mix of both non-fraudulent and fraudulent transactions. The project will include numerous ML algorithms like Decision Trees, Logistic Regression, Artificial Neural Networks, and Gradient Boosting Classifier.

By implementing these ML algorithms, the system will be able to tell apart a fraudulent call from a non-fraudulent one. This project will teach you how to apply ML algorithms in a real-world scenario to perform classification.

You can train the ML algorithm to identify anomalies after processing data across customer behavior, location, network, transaction value, payment method, etc. You can effectively build your classification engine for fraud detection by utilizing K-nearest neighbor, decision trees, support vector machine, logistic regression, XGBoost, and random forest.

Key challenges associated with credit card fraud detection:

You may come across the following challenges when working on your data science project ideas.

  • Huge data is processed daily, and the model build should be quick enough to respond to the fraud.
  • Imbalanced Data suggests that most of the transactions are not fraudulent. This makes it difficult to detect fraudulent transactions.
  • Data availability is one of the key challenges because the data is mostly private.
  • Misclassified Data is another challenge because not all fraudulent transactions are detected and reported.
  • Adaptive techniques are used against the model by the fraudsters.

4. Movie Recommendation project

If you’re an avid lover of Amazon, Amazon Prime, or Netflix, you probably know that these platforms leverage “recommendation engines.” As you can guess by the name, a recommendation engine sole purpose is to “recommend” relevant things to customers – while for Amazon it recommends products, for Prime and Netflix it recommends content to users, based on their previous purchase history or watch history. 

The main goal of this R project is to design a recommendation system that will recommend movies to users. The dataset used for this project is MovieLens dataset. This data includes 105339 ratings for over 10329 movies. In this project, you will create an Item Based Collaborative Filter.

The best part about building this movie recommendation engine from scratch is that it will help you understand the inner functioning and mechanism of a recommendation engine. You will learn how to implement your R programming skills along with Machine learning skills in a live project.

The movie recommendation system recommends the next movie to the users using Collaborative filtering. It analyzes different factors like movie rating, movie similarity, user similarity, etc. It is one of the prevalent data science project ideas among movie lovers. Its working process involves the following steps:

1. Data Preprocessing:

This step loads the ratings.csv file and movies.csv file into the system and then processes them.  It classifies the movies depending on the genre.

2. Analysis:

In this step, the data available in the system are analyzed depending on user similarity, ratings, number of watches, etc.

3. Recommendation:

It recommends movies based on the analysis and recommendation matrix provided.

5. Music Recommendation project 

You may wonder how you receive song recommendations of your choice when playing songs online. The reason is the relevant platforms use machine learning models to recommend the songs they think you would listen to. It is extensively used in many SQL projects for data analysis.

A music recommendation system works similarly to a movie recommendation system, the only difference being that instead of movies, it will recommend music to users. This is a Python + R project. The dataset used for this project is from KKBOX, the leading music streaming service in Asia, boasting of a library containing over 30 million music tracks

In this project, you will build an ML system using Python and R that can predict the chances of a user listening to a song on loop after the first listening event was triggered within a specific time window. Here, the training and test datasets are chosen from the listening history of different users in a given time period.

So, for instance, if a recurring listening event(s) triggers within a month after a user’s first observable listening event, the system marks the target as 1 in the training set, and otherwise, it marks 0. The same rule is then applied to the test set. This project is the perfect opportunity to learn how to perform basic EDA to derive insights from the data.

6. Customer Segmentation project

Just like Sentiment Analysis is used to gain deeper insights into the customers’ opinions and emotions about different products/services, Customer Segmentation is used for more targeted marketing. By categorizing the target audience into different buyer personas according to their needs, preferences, age, location, job, purchasing behavior, etc., brands can create customized products, marketing strategies, and offers/discounts, for a specific customer segment. This allows for higher customer satisfaction which eventually boosts the sales and revenue. 

Customer Segmentation is one of the most extensively used applications of unsupervised learning (ML). In this project, you will use the K-means algorithm for clustering an unlabeled dataset. The K-means clustering algorithm can effectively visualize the age and gender distributions in the dataset. Further, it will also analyze annual incomes and spending patterns. Essentially, this R project will offer a descriptive analysis of the data by implementing varied versions of the K-means algorithm.

The customer segmentation technique depends on various key differentiators that categorize customers into groups. The data associated with geography, demographics, economic status, and behavioral patterns play a vital role in deciding the company’s path toward solving different segments.

The companies can attain an in-depth understanding of customers’ preferences and customers’ requirements based on the data collected. This understanding helps them to discover valuable segments that would provide them with maximum profit. As a result, they can manipulate their marketing techniques more competently and reduce the odds of risk in their investment. It is one of the most commonly used SQL projects for data analysis for targeted marketing.

7. Product Bundle Identification project

The concept of product bundling is nothing new in the field of marketing. In the product bundling approach, different products are clubbed together and sold as a single unit at a specific price (usually discounted price). This allows marketers to encourage customers to buy more of their products. Perhaps the best example of a product bundle is McDonald’s Happy Meal. 

In this Data Science project, the primary focus will be on subjective segmentation, a clustering technique that can help identify the best product bundles in sales data. Here, we will take a weekly sales transaction dataset containing the purchased quantities of different products over the span of a few weeks.

The dataset will also include normalized values. By using this dataset, the goal is to find out which products can be bundled together to make excellent combos for customers. While the traditional approach uses the Market Basket Analysis to identify product bundles, in this project, our focus is to compare and analyze the relative importance of time series clustering in determining product bundles from sales data.

8. Wine Quality Prediction project

The idea here is to improve wine quality using predictive modeling. In this Data Science project, we will analyze a red wine dataset to assess the wine quality. The objective of this project is to explore the chemical properties that influence the quality of red wine.

In the project, the first consideration is to use the input variables to predict the wine quality, whereas the second consideration is to classify wines having excellent attributes. You will create and refine plots to illustrate the unique relationships in the data as and when they are uncovered. The project will teach you data exploration, data visualization, storytelling, and also how to apply regression models and ask the right questions for data analysis at different stages in the project.
