    Awol risk assessment l.jpg
    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.
