Code for our ACL 2021 paper - ConSERT: A Contrastive Framework for Self-Supervised Sentence Representation Transfer

Requirements

torch==1.6.0
cudatoolkit==10.0.103
cudnn==7.6.5
sentence-transformers==0.3.9
transformers==3.4.0
tensorboardX==2.1
pandas==1.1.5
sentencepiece==0.1.85
matplotlib==3.4.1
apex==0.1.0

Get Started

1. Download pre-trained language model (e.g. bert-base-uncased) from HuggingFace's Library
2. Download STS datasets to ./data folder using SentEval toolkit
3. Run the following script to run the unsupervised experiment:

   python3 main.py --no_pair --seed 1 --use_apex_amp --apex_amp_opt_level O1 --batch_size 96 --max_seq_length 64 --evaluation_steps 200 --add_cl --cl_loss_only --cl_rate 0.15 --temperature 0.1 --learning_rate 0.0000005 --train_data stssick --num_epochs 10 --da_final_1 feature_cutoff --da_final_2 shuffle --cutoff_rate_final_1 0.2 --model_name_or_path [PRETRAINED_BERT_FOLDER] --model_save_path ./output/unsup-base-feature_cutoff-shuffle --force_del --no_dropout --patience 10

   where [PRETRAINED_BERT_FOLDER] should be replaced to the folder that contains downloaded pre-trained language model
