java.lang.Object cc.mallet.fst.confidence.TransducerConfidenceEstimator cc.mallet.fst.confidence.ConstrainedForwardBackwardConfidenceEstimator
public class ConstrainedForwardBackwardConfidenceEstimator
Estimates the confidence of a Segment
extracted by a Transducer
by performing a "constrained lattice"
calculation. Essentially, this sums all possible ways this segment
could have been extracted and normalizes.
