Likewise, <em>endFeature</em> can be considered as a special edge feature which is from the last token to the very end. So m table encodes the edgeFeature, startFeature, and endFeature. If the total number of labels in the label space is 45 from 0 to 44, then the m factor array is as follows: </p><pre> + 0 1 2 3 4 5...44 +startFeature -1 a a a a a a...a +edgeFeature 0 a a a a a a...a +edgeFeature 1 a a a a a a...a +... +edgeFeature 44 a a a a a a...a +endFeature 45 a a a a a a...a</pre><ul> +<li>viterbi_r table is related to specific tokens. It encodes the single state features, e.g., wordFeature, RegexFeature for all tokens.
