Challenge: a vast majority of language pairs in the world are considered low-resource because they have little parallel data available.
Approach: They propose to use a dataset to evaluate methods trained on low-resource language pairs . they report baseline performance using supervised, weakly supervised and semi-supervised settings .
Outcome: The proposed evaluation datasets show that current state-of-the-art methods perform poorly on this benchmark, posing a challenge to the research community working on low-resource MT.
