AWOL Risk Assessment

Collected nearly 150,000 records on eBay users

In experimental phase, used up to 80,000 records for training. Resulted in over-learning but identified important attributes.

In production phase, used 13,000 specially selected records to train and 50,000 to test. Achieved between 95% and 98% accuracies on predicting if the user became unregistered in the last thirty days.
