"Evolutionary, my dear Watson" - Investigating Committee-based Evolution of Fuzzy Rules for the Detection of Suspicious Insurance Claims

Fraud is causing huge losses to our financial world. This work describes the use of a committee decision system using genetic programming to evolve fuzzy logic rules capable of detecting suspicious home insurance claims. Details of the evolutionary-fuzzy system, the committee decision maker and the data preprocessing are provided. Finally, a series of experiments are described, showing that the complete system is capable of attaining good accuracy and intelligibility levels for real home insurance data.
