Weijia Xu, Marine Jacinthe Carpuat · 2018
This paper describes the University of Maryland's submission to the WMT 2018 Chinese↔English news translation tasks.Our systems are BPE-based self-attentional Transformer networks with parallel and backtranslated monolingual training data.Using ensembling and reranking, we improve over the Transformer baseline by +1.4 BLEU for Chinese→English and +3.97 BLEU for English→Chinese on newstest2017.Our best systems reach BLEU scores of 24.4 for Chinese→English and 39.0 for English→Chinese on newstest2018.
