• Fast Combinatorial Feature Selection with New Definition of Predictive Power

    Originally posted on DataScienceCentral, by Dr. Granville. Click here to read original article and comments. In this article, I proposes a simple metric to measure predictive power. It is used for combinatorial feature selection, where a large number of feature combinations need to be ranked automatically and very fast, for instance in the context of transaction...

This is a component often missing, yet valuable for most systems, algorithms and architectures that are dealing with online or mobile data, known as digital data: be it transaction scoring, fraud detection, online marketing, marketing mix and advertising optimization, online...

  • Hidden decision trees revisited – Data Science Central

    Originally posted on DataScienceCentral, by Dr. Granville. Click here to read original article and comments. Hidden decision trees (HDT) is a technique patented by Dr. Granville, to score large volumes of transaction data. It blends robust logistic regression with hundreds small decision trees (each one representing for instance a specific type of fraudulent transaction) and offers significant...
