Biswajit Pal, Subhasish Mishra and Manav Shroff - Predicting Repeat Purchase Behavior

A major question in database marketing is that of identifying the customers who are most likely to make a repeat purchase in the near future. In this session at The Fifth Elephant 2012, Biswajit Pal, Subhasish Mishra and Manav Shroff from HP discuss a scalable repeat purchase scoring algorithm that assigns a propensity score i.e. probability to transact in next 'n' period of time for each customer. This algorithm presently scores an entire database containing around 100MM customers in couple of hours and thus has the potential to be used in a Big Data scenario.
