tf.contrib.crf.crf_decode

Decode the highest scoring sequence of tags in TensorFlow.

tf.contrib.crf.crf_decode(
    potentials, transition_params, sequence_length
)

This is a function for tensor.

Args
potentials	A [batch_size, max_seq_len, num_tags] tensor of unary potentials.
transition_params	A [num_tags, num_tags] matrix of binary potentials.
sequence_length	A [batch_size] vector of true sequence lengths.

Returns
decode_tags	A [batch_size, max_seq_len] matrix, with dtype tf.int32. Contains the highest scoring tag indices.
best_score	A [batch_size] vector, containing the score of decode_tags.
