I don't see any reason why a lattice should contain an EPSILON edge. In a confusion network, EPSILON are needed to allow the translation of input of different lengths. The sausage structure of the CN imposes the same amount of source words, and the EPSILONs overcome this constraint.
This is not the case for lattice, because you can have any number of edges/words in a complete source path. cheers, Nicola On Oct 4, 2013, at 2:52 PM, Hieu Hoang wrote: I'm just looking at the lattices decoding, as implemented in moses. for confusion networks, it's fair to have EPSILON words (that represent blank words). However, I don't see the point of them in lattices. Anyone have an opinion?
