Modeling Past and Future for Neural Machine Translation
(b) Source summarization is not fully exploited by NMT decoder.
['Initialize Decoder States with …', 'BLEU']
We also experiment to not feed the source summarization into the decoder of the proposed model, which leads to a significant BLEU score drop on Zh-En. This shows that our proposed model better use the source summarization with explicitly modeling the Future compared to the conventional encoder-decoder baseline.
