gated-Transformer

Gated Pretrained Transformer model for robust denoised sequence-to-sequence modeling. It uses a gating unit to detect and correct noises from text data and generate de-noised target from a generative decoder.

In this work we conduct our experiment on three tasks -

• Denoising corrputed text
• Denoised machine translation
• Denoise summarization

gated-Transformer is shown effective on -

• OCR noise
• Random spelling mistakes
• Keyboard based noises
• Insertion, Deletion, Swapping based noises

Installation for experiments

$ pip install -r requirements.txt

Commands to run

Training a denoiser

pretrained transformer sequence-to-sequence model (e.g. - BART, T5)

$ cd ./drive/MyDrive/gated-denoise/ && python train.py --train_file ./data.csv \
                                                  --model_path ./model/ --model_type bart --pretrained_encoder_path "facebook/bart-base" \
                                                  --mask_gate --copy_gate --generate_gate --skip_gate \
                                                  --epochs 15

Transformer encoder-decoder model (e.g. - BERT2BERT)

$ cd ./drive/MyDrive/gated-denoise/ && python train.py --train_file ./data.csv \
                                                  --model_path ./model/ --model_type seq2seq \
                                                  --pretrained_encoder_path "bert-base-uncased" --pretrained_decoder_path "bert-base-uncased" \
                                                  --mask_gate --copy_gate --generate_gate --skip_gate \
                                                  --epochs 15

Inference

$ cd ./drive/MyDrive/gated-denoise/ && python predict.py --data_file ./data.csv \
                                                  --model_path ./model/ --model_type bart --pretrained_encoder_path "facebook/bart-base" \
                                                  --mask_gate --copy_gate --generate_gate --skip_gate
