Before revision:  As a proof of concept we show that a straightforward implementation of minimum Bayes risk decoding gives good results outperforming beam search using as little as 30 samples, confirming that MLE-trained NMT models do capture important aspects of translation well in expectation.
After revision:  As a proof of concept we show that a straightforward implementation of minimum Bayes risk decoding gives competitive results confirming that NMT models do capture important aspects of translation well in expectation.
