Sukanta Sen, Kamal Kumar Gupta, Asif Ekbal, Pushpak Bhattacharyya · 2019
We describe our submission to WMT 2019 News translation shared task for Gujarati-English language pair.We submit constrained systems, i.e, we rely on the data provided for this language pair and do not use any external data.We train Transformer based subword-level neural machine translation (NMT) system using original parallel corpus along with synthetic parallel corpus obtained through back-translation of monolingual data.Our primary systems achieve BLEU scores of 10.4 and 8.1 for Gujarati→English and English→Gujarati, respectively.We observe that incorporating monolingual data through back-translation improves the BLEU score significantly over baseline NMT and SMT systems for this language pair.
