Webterminal_var = forward_var + self.transitions [self.tag_to_ix [STOP_TAG]] # Follow the back pointers to decode the best path. # Pop off the start tag (we dont want to return that to the caller) def forward (self, sentence): # dont confuse this with _forward_alg above. # Find the best path, given the features. Webtransition score between state pand q, is log(1=10) if there is only one p )qtransition out of 10 transitions starting with the state p. We set the scores of all unseen transitions to inf. As for CRF emission scores, we use the state prediction logits from T5. In contrast with previous methods, which treat each step equally, we weigh the WebCRF. This module implements a Conditional Random Field (CRF). The forward computation of this class computes the log likelihood of the given sequence of tags and emission score tensor.
