Effective Cross-lingual Transfer of Neural Machine Translation Models without Shared Vocabularies
Table 6: Slovenian→English translation results with freezing different components of the decoder.
['Frozen parameters', 'Bleu [%]']
We show only the results when freezing the decoder; in our experiments, freezing any component of the encoder always degrades the translation performance. The experiments were done at the final stage with all of our three proposed methods applied.
