Movie Recommendation System

Built an hybrid recommendation model on "Movielens" DataSet that includes over 100 millions ratings. Our model in- cludes 4 different modes based on 4 types user input( null, MoiveID, UsrId Or Moive and UsrID).

This system is able to predict movie ratings based on how the other users have predicted the movie.

Build an engine that gave movie suggestions to a particular user based on the estimated ratings that it had internally cal- culated for that user.

Playing DoomwithaRecurrentNetwork

Trained a reinforcement learning agent (combined with Double Deep Recurrent Network) in ViZDoom.

The AI agent was able to play the game Doom,attacking the enemy and survived automatically. Node-Based Resilience Graph Theoretic Framework Designed

Designed the graph based clustering algorithm to distinguish subgroups of Autism Spectrum Disorder (ASD). Used graph quality measures, internal cluster validation measures, and clinical analysis outcome to demonstrate the potential useful- ness of resilience measure for biomedical datasets. Facial Detection for Class Attendance

Developed an transfer learning Matrix as an head classifier to detect faces in the class

Different camera angle, position, image quality were the major challenges. The overall accuracy up to 90%. Object Recognition for Robot

Built an robot car on a raspberry Pi and implemented an object recognition model with deep neural networks.

The robot car is able to recognize traffic signs and avoid obstacles on its own. Implementation of Genetic algorithm

Using Genetic algorithm to provide optimal solution for “2-D-Jump-It game” whose goal is to move the character from the first cell to the last cell with the lowest total cost. Employee Database Design

Designed a software used for progression tracking and job scheduling for employee’s daily opeartion. Implemented in Python, SQL, and TCP/IP.

Multi-objective Optimization Approach to Find Biclusters.

Designed evolutionary based biclustering algorithm to find meaningful biclusters in gene expression data. Provided infor- mation about the effects of disease at genetic level. Key contributions include synthetic data generation, improvement of recovery and relevance measures.
