Pivot-based Transfer Learning for Neural Machine Translationbetween Non-English Languages
Table 4: Cross-lingual encoder variations (French→ German). All results are in the zero-shot setting with step-wise pre-training.
['Trained on', 'Input', 'newstest2013 Bleu [%]', 'newstest2013 Ter [%]']
It improves the final translation performance by maximum +2.1% Bleu, compared to using the copying autoencoding objective.
