tf.contrib.crf.crf_unary_score(
    tag_indices, sequence_lengths, inputs
)

Args
tag_indices	A [batch_size, max_seq_len] matrix of tag indices.
sequence_lengths	A [batch_size] vector of true sequence lengths.
inputs	A [batch_size, max_seq_len, num_tags] tensor of unary potentials.

Returns
unary_scores	A [batch_size] vector of unary scores.
