Overview

The implementation of Parameter Differentiation based Multilingual Neural Machine Translation .

Requirement:

apex
fairseq
scikit-learn
pytorch
  1. Process data following https://github.com/pytorch/fairseq/tree/main/examples/translation#multilingual-translation.
  2. Training:
data_bin=    # data path 
lang_pairs=  # comma separated language pairs

fairseq-train $data_path \
    --task parameter_differentiation_task --lang-pairs $lang_pairs --encoder-langtok tgt \
    --criterion label_smoothed_cross_entropy --label-smoothing 0.1 \
    --optimizer adam --lr 0.0015 --adam-betas '(0.9,0.98)' \
    --lr-scheduler inverse_sqrt --warmup-updates 4000 --warmup-init-lr 1e-07 \
    --arch parameter_differentiation_base_model \
    --max-tokens 8192 \
    --user-dir $PWD 
  1. Decoding
source_lang=
