Massively Multilingual Neural Machine Translation

Aharoni, Roee, Johnson, Melvin, Firat, Orhan

Understand

Multilingual neural machine translation (NMT) enables training a single model that supports translation from multiple source languages into multiple target languages.

  • In this paper, we push the limits of multilingual NMT in terms of number of languages being used.
  • We perform extensive experiments in training massively multilingual NMT models, translating up to 102 languages to and from English within a single model.
  • We explore different setups for training such models and analyze the trade-offs between translation quality and various modeling decisions.
