Computes the unnormalized score for a tag sequence.
crf_sequence_score(inputs, tag_indices, sequence_lengths, transition_params)
| inputs | A [batch_size, max_seq_len, num_tags] tensor of unary potentials to use as input to the CRF layer. |
|---|---|
| tag_indices | A [batch_size, max_seq_len] matrix of tag indices for which we compute the unnormalized score. |
| sequence_lengths | A [batch_size] vector of true sequence lengths. |
| transition_params | A [num_tags, num_tags] transition matrix. Returns: |
sequence_scores: A [batch_size] vector of unnormalized sequence scores.
