Data Science Projects:

I)Real Estate : A real estate agency wanted to reduce the negotiation time and improve closure for buyers and sellers of homes by ensuring that both sides were advised well on the potential sale/purchase price of the home. To that end the agency wanted to predict a transaction price for all the houses in its market which would be as close as possible to a price where the transaction would take place. Data regarding all possible variables and qualities of over 10,000 houses sold in the past was collected and analyzed.

Solution: Created a predictive model using linear regression to arrive at a potential transaction price for all future transactions. Over the next 6 months, negotiation time was brought down from 3 weeks on average to 8 days. Deal closure went up by 28%.

II)Banking: A bank in Portugal was rolling out a new term deposits product for its existing customers. They wanted to understand which of their existing customers to call and target for this new product so that ROI would be high. In the past they had connected to their customer base through phone calls for various other products. Results for these previous campaigns had been made available for over 50,000 customers.

Solution: Used Logistic regression to create a propensity model to predict those customers most likely to respond positively to the new product and the campaign. Model had an accuracy of 85% and increased campaign ROI by 78%.
