On the Relationship between Neural Machine Translation and Word Alignment

no code implementations Xintong Li, Lemao Liu, Guanlin Li, Max Meng, Shuming Shi

We find that although NMT models are difficult to capture word alignment for CFT words but these words do not sacrifice translation quality significantly, which provides an explanation why NMT is more successful for translation yet worse for word alignment compared to statistical machine translation.
