Examples of org.encog.ml.hmm.alog.KullbackLeiblerDistanceCalculator

org.encog.ml.hmm.alog.KullbackLeiblerDistanceCalculator
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). "On Information and Sufficiency". Annals of Mathematical Statistics 22 (1): 79-86. doi:10.1214/aoms/1177729694. MR39968.
