Before revision:  We introduce  a novel MT training method that approximates the full space of possible translations by : sampling a paraphrase of the reference sentence from a paraphraser and training the MT model to predict the paraphraser's distribution over possible tokens.
After revision:  We introduce Simulated Multiple Reference Training (SMRT), a novel MT training method that approximates the full space of possible translations by : sampling a paraphrase of the reference sentence from a paraphraser and training the MT model to predict the paraphraser's distribution over possible tokens.
