tfa.text.crf_log_norm(
    inputs: tfa.types.TensorLike,
    sequence_lengths: tfa.types.TensorLike,
    transition_params: tfa.types.TensorLike
) -> tf.Tensor

Args

`sequence_lengths`	A [batch_size] vector of true sequence lengths.
`transition_params`	A [num_tags, num_tags] transition matrix.

Returns
`log_norm`	A [batch_size] vector of normalizers for a CRF.
