LIUM Machine Translation Systems for WMT17 News Translation Task

Abstract : This paper describes LIUM submissions to WMT17 News Translation Task for English↔German, English↔Turkish, English→Czech and English→Latvian language pairs. We train BPE-based attentive Neural Machine Translation systems with and without factored outputs using the open source nmtpy framework. Competitive scores were obtained by en-sembling various systems and exploiting the availability of target monolingual corpora for back-translation. The impact of back-translation quantity and quality is also analyzed for English→Turkish where our post-deadline submission surpassed the best entry by +1.6 BLEU.
