Description copied from class: SumLatticeFactory

Returns a SumLattice object to run forward-backward.

Specified by:

newSumLattice in class SumLatticeFactory

Parameters:

trans - Transducer model

input - Input sequence

output - If output is null then the forward-backward is not constrained to match the output

incrementor - If null then do not update the weights

saveXis - If true then save the transition weights as well

outputAlphabet - If outputAlphabet is non-null, this will create a LabelVector for each position in the output sequence indicating the probability distribution over possible outputs at that time index.
