Pytorch bilstm_crf
Web众所周知,通过Bilstm已经可以实现分词或命名实体标注了,同样地单独的CRF也可以很好的实现。 既然LSTM都已经可以预测了,为啥要搞一个LSTM+CRF的hybrid model? 因为单独LSTM预测出来的标注可能会出现(I-Organization->I-Person,B-Organization ->I-Person)这样的问题序列。 但这种错误在CRF中是不存在的,因为CRF的特征函数的存在就是为了对输 … Webpytorch-crf ¶ Conditional random fields in PyTorch.

WebThis changes the LSTM cell in the following way. First, the dimension of h_t ht will be changed from hidden_size to proj_size (dimensions of W_ {hi} W hi will be changed accordingly). Second, the output hidden state of each layer will be multiplied by a learnable projection matrix: h_t = W_ {hr}h_t ht = W hrht.
