Query: Later-stage Minimum Bayes-Risk Decoding for Neural Machine Translation   For extended periods of time, sequence generation models rely on beam search
algorithm to generate output sequence. However, the correctness of beam search
degrades when the a model is over-confident about a suboptimal prediction. In
this paper, we propose to perform minimum Bayes-risk (MBR) decoding for some
extra steps at a later stage. In order to speed up MBR decoding, we compute the
Bayes risks on GPU in batch mode. In our experiments, we found that MBR
reranking works with a large beam size. Later-stage MBR decoding is shown to
outperform simple MBR reranking in machine translation tasks.
