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.
