A fast finite-state relaxation method for enforcing global constraints on sequence decoding
Roy W. Tromble, Jason M. Eisner · 2006
We describe finite-state constraint relaxation, a method for applying global constraints, expressed as automata, to sequence model decoding. We present algorithms for both hard constraints and binary soft constraints. On the CoNLL-2004 semantic role labeling task, we report a speedup of at least 16x over a previous method that used integer linear programming.
