Adversarial Mutual Information for Text Generation
Table 5: Machine translation results of the BLEU scores on WMT English-German for newstest2014.
['[BOLD] Models', '[BOLD] En→De', '[BOLD] De→En']
Similar to the results of dialog generation, our AMI framework improves upon both the LSTM and Transformer, and outperforms the MMI for about 1.4 BLEU scores. We also find that the improvement from LNS is quite modest, and we conjecture this is because the NMT task has the nature that the semantics of the target are fully specified by the source.
