Interface LocalPathSimilarityScore

All Known Implementing Classes:

public interface LocalPathSimilarityScore

interface for local scoring functions used by the local score gradient functions. The alternate objective functions that use a local similarity score to calculate use this interface to access the local scoring functions.

Method Summary

double

evaluate(int yprev, int y, TrainingSequence<?> seq, int pos) compute a real-valued score between a given path and the true path at a given position.

Method Detail

evaluate

double evaluate(int yprev,
                int y,
                TrainingSequence<?> seq,
                int pos)

compute a real-valued score between a given path and the true path at a given position.

Parameters:

yprev - the hidden state at the previous position in this path

y - the hidden state at the current position in this path

seq - the training sequence containing the input and the true path

pos - the position at which the score is to be calculated

Returns:

the similarity score computed at this position for this path
