Advances and Challenges in Unsupervised Neural Machine Translation
Rui Wang, Hai Yan Zhao · 2021
Unsupervised cross-lingual language representation initialization methods, together with mechanisms such as denoising and backtranslation, have advanced unsupervised neural machine translation (UNMT), which has achieved impressive results.Meanwhile, there are still several challenges for UNMT.This tutorial first introduces the background and the latest progress of UNMT.We then examine a number of challenges to UNMT and give empirical results on how well the technology currently holds up 1 .
