Research Interest and Reading

My research interest lies in the field of Natural Language Processing and Machine Learning.

I worked on the Netflix Prize problem as my researc project under the guidance of Dr. Richard Maclin. We proposed an algorithm to solve this problem by clustering the users in the movie domain based on the similarity between them in the genre of the movies they have rated. Our method achieved accuracy better than the current Netflix implementation and is faster than the Naive k-NN impplementation. This project provided my with an opportunity to research the domain of Collaborative Filtering and its application to various day to day problems. 

Here is the link to my defense presentation.
