16 Data Mining Projects Ideas & Topics For Beginners [2020]

Today, data mining has become strategically important to organizations across industries. It not only helps in predicting outcomes and trends but also in removing bottlenecks and improving existing processes. If you are just getting started in data science, making sense of advanced data mining techniques can seem daunting. So, we have compiled some useful data mining project topics to support you in your learning journey.

But before we begin, let us look at an example to decode what data mining is all about. Suppose you have a data set containing login logs of a web application. It can include things like the username, login timestamp, activities performed, time spent on the site before logging out, etc.

Such unstructured data in itself would not serve any purpose unless it is organized systematically and analyzed to extract relevant information for the business. By applying the different techniques of data mining, you can discover user habits, preferences, peak usage timings, etc. These insights can further increase the software system’s efficiency and boost its user-friendliness. Learn more about the differences between data mining and data science.

In today’s digital era, the computing processes of collecting, cleaning, analyzing, and interpreting data make up an integral part of business strategies. So, data scientists are required to have adequate knowledge of methods like pattern tracking, classification, cluster analysis, prediction, neural networks, etc. 

Data Mining Project Ideas & Topics for Beginners

1. iBCM: interesting Behavioral Constraint Miner

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.

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.

2. GERF: Group Event Recommendation Framework

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.

This model uses a learning-to-rank algorithm to extract group preferences and can incorporate additional contextual influences with ease, accuracy, and time-efficiency. Also, it can be conveniently applied to other group recommendation scenarios like location-based travel services. 

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.

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.

This problem calls for innovative data mining projects that can catch the transitive interactions between graph nodes. 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.)  

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. 

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. 

6. Protecting user data in profile-matching social networks

Consider the user profile database maintained by the providers of social networking services, such as online dating sites. The querying users specify certain criteria based on which their profiles are matched with that of other users. This process has to be secure enough to protect against any kind of data breaches. There are some solutions in the market today that use homomorphic encryption and multiple servers for matching user profiles to preserve user privacy. 

7. PrivRank for social media

Social media sites mine their users’ preferences from their online activities to offer personalized recommendations. However, user activity data contains information which can be used to infer private details about an individual (for example, gender, age, etc.) And any leak or release of such user-specified data can increase the risk of interference attacks. 

8. Practical PEKs scheme over encrypted email in cloud server

In the light of current high-profile public events related to email leaks, the security of such sensitive messages has emerged as a primary concern for users worldwide. To that end, the Public Encryption with Keyword Search (PEKS) technology offers a viable solution. It combines security protection with efficient search operability functions. 

When searching over a sizable encrypted email database in a cloud server, we would want the email receivers to perform quick multi-keyword and boolean searches without revealing additional information to the server.

9. 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 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

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.

12. Social-Aware social influence modeling

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

Experimental results reveal that the structure of this proposed solution enables higher prediction accuracy as compared to other baseline methods. 

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. 

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. 

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 project 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. 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).

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. 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
