... available in very limited domains and building bilingual re- sources in a new domain is usually very expensive. It is an interesting question whether a model that is trained on an existing large bilingual ... concate- nation baseline. In particular, Switching:Max could gain up to 2.2 BLEU points over the concatenation baseline and 0.39 BLEU points over the best per- forming baseline (i....
