City University of New York – SPS

Movie Recommendation: Building algorithms using UBCF, IBCF, contextual data in SprakR with AWS.

Bike Rental Simulation: Simulation of a bike rental model using Simio. Simulated different scenarios to get the best optimal bike renting rate for maximum profit.

Analysis of literacy of India : The project involves analysis of literacy data of India and data mining for interesting results to create a report with the visualizations using R, PostgresSql and MongoDb, JSON.

Analysis of sale data of groupon.com : The project is to find if any relationship exists between the deal price and the rate of sell. The project and the analysis were done using Python(panda, numpy, BeautifulSoup). Though we couldn’t find any direct correlation between deal price and rate of sale, but there is some interesting correlation if we analyze by product type.
