crf_forward

A [batch_size, num_tags] matrix of unary potentials.

inputs

A [batch_size, num_tags] matrix containing the previous alpha values.

state

A [num_tags, num_tags] matrix of binary potentials. This
matrix is expanded into a [1, num_tags, num_tags] in preparation for the broadcast
summation occurring within the cell.

transition_params

A [batch_size] vector of true sequence lengths.

sequence_lengths

Computes the alpha values in a linear-chain CRF.

'TensorFlow SIG Addons' <https://www.tensorflow.org/addons> is a repository
of community contributions that conform to well-established API patterns,
but implement new functionality not available in core 'TensorFlow'.
'TensorFlow' natively supports a large number of operators, layers, metrics,
losses, optimizers, and more. However, in a fast moving field like Machine Learning,
there are many interesting new developments that cannot be integrated into
core 'TensorFlow' (because their broad applicability is not yet clear, or
it is mostly used by a smaller subset of the community).
