The AFRL WMT19 Systems: Old Favorites and New Tricks

Jeremy Gwinnup, Grant Erdmann, Tim Anderson

Abstract: This paper describes the Air Force Research Laboratory (AFRL) machine translation systems and the improvements that were developed during the WMT19 evaluation campaign. This year, we refine our approach to training popular neural machine translation toolkits, experiment with a new domain adaptation technique and again measure improvements in performance on the Russian–English language pair.
