WebRecall that the CRF computes a conditional probability. Let y y be a tag sequence and x x an input sequence of words. Then we compute P (y x) = \frac {\exp { (\text {Score} (x, y)})} {\sum_ {y'} \exp { (\text {Score} (x, y')})} P (y∣x) = ∑y′ exp(Score(x,y′))exp(Score(x,y)) WebSource code for torchcrf. __version__ = '0.7.2' from typing import List, Optional import torch import torch.nn as nn.
