state	A [batch_size, num_tags] matrix containing the previous step's score values.
transition_params	A [num_tags, num_tags] matrix of binary potentials.
sequence_lengths	A [batch_size] vector of true sequence lengths.

Returns
backpointers	A [batch_size, num_tags] matrix of backpointers.
new_state	A [batch_size, num_tags] matrix of new score values.
