M2M100 : multilingual translation model

M2M100 is a multilingual encoder-decoder (seq-to-seq) model trained for Many-to-Many multilingual translation.

The model can directly translate between the 9,900 directions of 100 languages.

Pretrained models can be loaded with pretrained of the companion object:

val m2m100 = M2M100Transformer.pretrained()
  .setInputCols("document")
  .setOutputCol("generation")

The default model is "m2m100_418M", if no name is provided. For available pretrained models please see the Models Hub.

For extended examples of usage, see M2M100TestSpec.

Paper Abstract:

Existing work in translation demonstrated the potential of massively multilingual machine translation by training a single model able to translate between any pair of languages. However, much of this work is English-Centric by training only on data which was translated from or to English. While this is supported by large sources of training data, it does not reflect translation needs worldwide. In this work, we create a true Many-to-Many multilingual translation model that can translate directly between any pair of 100 languages. We build and open source a training dataset that covers thousands of language directions with supervised data, created through large-scale mining. Then, we explore how to effectively increase model capacity through a combination of dense scaling and language-specific sparse parameters to create high quality models. Our focus on non-English-Centric models brings gains of more than 10 BLEU when directly translating between non-English directions while performing competitively to the best single systems of WMT. We open-source our scripts so that others may reproduce the data, evaluation, and final M2M-100 model.
