Example for Neural Machine Translation (NMT) experiments.

• A PyTorch installation (0.4.0) and install fairseq with:

pip install -r ./fairseq_mix/requirements.txt
python ./fairseq_mix/setup.py build develop

• install FastBPE
• install mosesdecoder

• Prepare BPE data, refer to data_prepare

• Prepare SentencePiece (SP) data, learning SP vocabulayr and tokenized data by running:

python sen_piece_learn.py

• Preprocess the BPE and SP data by running:

python preprocess.py 

• Pre-train mix_presentation model

bash ruuning_scripts/train_mix_iwslt14_emb256.sh 

• Generate the translation data for self-training (co-teaching data generation)

bash infer_and_process_train_data.sh 

• Self-training models (co-teaching model training)

bash ruuning_scripts/train_mix_iwslt14_emb256_reset_trans.sh 

1. Infer pre-train model (mix_representation model)

bash ruuning_scripts/infer_iwslt_emb256.sh 

2. Infer self-training model (co-teaching model)

bash running_scripts/infer_iwslt_emb256_reset_trans.sh
