Multilingual Neural Machine Translation with Task-Specific Attention
Table 5: BLEU scores for single-data baseline and task-specific attention model variants: xx-to-En
['single-data', 'En-Fr 32.24', 'En-Fr 32.44', 'En-Fr 32.87', 'En-Es 32.60', 'En-Es 32.60', 'En-Es 33.18', 'En-De 22.15', 'En-De 22.55', 'En-De 22.36']
In all six translation directions, the single-data baseline systems obtain the highest overall BLEU scores. We expect these baseline models to perform well on their respective test sets since the translation direction (i.e. task) of the test set exactly matches the parallel data and validation set used to train the models.
