viterbi_decode(
    score,
    transition_params
)

Defined in tensorflow/contrib/crf/python/ops/crf.py.

See the guide: CRF (contrib)

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.
