Decode the highest scoring sequence of tags outside of TensorFlow.

This should only be used at test time.


  • score: A [seq_len, num_tags] matrix of unary potentials.
  • transition_params: A [num_tags, num_tags] matrix of binary potentials.


  • viterbi: A [seq_len] list of integers containing the highest scoring tag indices.
  • viterbi_score: A float containing the score for the Viterbi sequence.
