Effective Strategies in Zero-Shot Neural Machine Translation
Table 2: Results of the popular mix-language methods applied to German→Dutch and German→Romanian zero-shot tasks.
['[EMPTY]', '[BOLD] System', '[BOLD] Zero-shot?', '[BOLD] German→Dutch dev2010', '[BOLD] German→Dutch tst2010', '[BOLD] German→Romanian dev2010', '[BOLD] German→Romanian tst2010']
First we applied the baseline systems with respect to the IWSLT17 zero-shot tasks. Interestingly, the Back-Trans performed better that the direct approach on German→Romanian. We spectaculate that back translation might pose some translation noise which makes the translation from German→Romanian more robust.
