Refining Source Representations with Relation Networks for Neural Machine Translation
Table 4: Comparison of alignment quality on NIST Zh-En translation task.
['[BOLD] Systems', '[BOLD] BLEU', '[BOLD] AER']
It illustrates that our system Rnmt can produce better translations than the baseline RNNsearch⋆, a difference of 1.72 BLEU points. Besides, the AER score is 1.1 points lower than the baseline model. Note that the smaller the AER score, the better the alignment quality.
