tf.contrib.crf.viterbi_decode(score, transition_params)
Decode the highest scoring sequence of tags outside of TensorFlow.
This should only be used at test time.
Args:
score: A [seq_len, num_tags] matrix of unary potentials.
transition_params: A [num_tags, num_tags] matrix of binary potentials.
Returns:
viterbi: A [seq_len] list of integers containing the highest scoring tag indicies.
viterbi_score: A float containing the score for the viterbi sequence.
