  1. Three Recent Applications of the Unsupervised PRIDIT Predictive Modeling Technique: Fraud, Medical Care Quality, and Risk management Moderator: Richard A. Derrig, Opal Consulting LLC Speakers: Jing Ai, University of Hawaii Robert Liberthal, Jefferson School of Population Health James Guszcza, Delloitte Consulting CAS RPM Seminar March 21, 2011 New Orleans, LA

  2. Supervised learning Most common situation A dependent variable Frequency Loss ratio Fraud/no fraud Some methods Regression CART Some neural networks MARS Logistic Regression Naïve Bayes Unsupervised learning No dependent variable Group like records together A group of claims with similar characteristics might be more likely to be fraudulent Ex: Territory assignment, Text Mining Some methods Association rules K-means clustering Kohonen neural networks PRIDIT Major Kinds of Predictive Modeling
