Method Detail

apply

SparseVector apply(SparseVector[] x,
                   int[] y)

apply the feature function to an entire sequence of y's

apply

SparseVector apply(SparseVector[] x,
                   int ymt1,
                   int yt,
                   int t)

apply the feature function to a pair of tags (label positions)

Parameters:

x - entire input sequence

ytm1 - label at position t-1

yt - label at position t

t - position of interest. Should be 0<=t

wSize

int wSize()
