The code repository for the paper: Peijie Sun , Le Wu, Kun Zhang, Xiangzhi Chen, Meng Wang. Neighborhood-Enhanced Supervised Contrastive Learning for Collaborative Filtering (Accepted by TKDE).
The dataset can refer to following links(Baidu Netdisk, Google Drive).
The parameters files locate in config/amazon-book \ gowalla \ yelp2018 directories
As we have updated the proposed model name to NESCL, its previous name is SUPCCL, it can be found in the path recbole/model/general_recommender/supccl.py
To train the model, you should first prepare the training environment

pip install -r requirements.txt
python setup.py build_ext --inplace (We adopt the C++ evaluator in https://github.com/kuandeng/LightGCN)

Then, you can execute following commands to train the model based on different datasets:

python run_recbole_autodl.py --model=SUPCCL --dataset=yelp2018 --config=True --dataloader_file=/root/autodl-fs/yelp2018-for-SUPCCL-dataloader.pth
python run_recbole_autodl.py --model=SUPCCL --dataset=amazon-book --config=True --dataloader_file=/root/autodl-fs/amazon-book-for-SUPCCL-dataloader.pth
python run_recbole_autodl.py --model=SUPCCL --dataset=gowalla --config=True --dataloader_file=/root/autodl-fs/gowalla-for-SUPCCL-dataloader.pth

The generated log files saved in log directory, and the temporal model parameters can saved in the saved directory.
