Examples of ForwardBackwardScaledCalculator

org.encog.ml.hmm.alog.ForwardBackwardScaledCalculator
The forward-backward algorithm is an inference algorithm for hidden Markov models which computes the posterior marginals of all hidden state variables given a sequence of observations. This version makes use of scaling, and will not generate underflows with long sequences.
