• Rouge1: 0.3666
• Rouge2: 0.147
• Rougel: 0.3362
• Sacrebleu: 6.4622

Model description

Multilingual T5 (mT5) is a massively multilingual pretrained text-to-text transformer model, trained following a similar recipe as T5.

Intended uses & limitations

This is tried to be familiarized with the mt5 model in order to use it for the translation of English to Korean.

Training and evaluation data

This work was done as an exercise for English-Korean translation, so I trained by selecting only very small part of a very large original dataset. Therefore, the quality is not expected to be very good. 이 일은 영어 한국어 번역을 위한 연습으로 한 것이기 때문에 매우 큰 원 dataset에서 아주 작은 크기만의 글뭉치만 선택을 해서 훈련을 했다. 따라서 질은 그리 좋지 않을 것으로 예상된다.
