Class KullbackLeiblerDistanceCalculator

java.lang.Object

org.encog.ml.hmm.alog.KullbackLeiblerDistanceCalculator

public class KullbackLeiblerDistanceCalculator
extends java.lang.Object

This class produces a Kullback-Leibler estimation of the distance between two HMMs. This allows the similarity of two different HMM's to be evaluated. ^ Kullback, S.; Leibler, R.A. (1951).
