I see! Does this mean that the default decoding algorithm and MBR/consensus decoding are all trying to rerank the n-best list extracted from the search graph (in different ways)? If so, does it make sense at all to try to develop a search method to directly extract the best path from the search graph, i.e., the lattice?
