An Effective Approach to Unsupervised Machine Translation
Table 1: Results of the proposed method in comparison to previous work (BLEU). Overall best results are in bold, the best ones in each group are underlined. ∗Detokenized BLEU equivalent to the official mteval-v13a.pl script. The rest use tokenized BLEU with multi-bleu.perl (or similar).
['[EMPTY]', '[EMPTY]', 'WMT-14 fr-en', 'WMT-14 en-fr', 'WMT-14 de-en', 'WMT-14 en-de', 'WMT-16 de-en', 'WMT-16 en-de']
As it can be seen, our full system obtains the best published results in all cases, outperforming the previous state-of-the-art by 5-7 BLEU points in all datasets and translation directions.
