1. iBCM: interesting Behavioral Constraint Miner

One of the best ideas to start experimenting you hands-on data mining projects for students is working on iBCM. 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.

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.

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 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

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.

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
