Information Gain

This FS scheme is formed by two steps: a) an incremental feature ranking method, and b) an incremental learning algorithm that can consider a subset of the features during prediction (Naive Bayes).

Status

Use

val gain = InfoGainTransformer()
  .setNFeatures(2)
  .setSelectNF(1)

gain fit dataSet

val result = gain transform dataSet
