Please run the following command to install all the requirements:
pip install -r requirements.txtWe provide the trained models on Beauty, Sports_and_Outdoors, Toys_and_Games and ML-1M datasets in ./src/output/<Data_name>folder. You can directly evaluate the trained models on test set by running:
python main.py --data_name <Data_name> --model_idx 0 --do_eval --encoder SAS/GRU
On Beauty:
python main.py --data_name Beauty --model_idx 0 --do_eval --encoder SAS{'Epoch': 0, 'HIT@5': '0.0698', 'NDCG@5': '0.0494', 'HIT@10': '0.0959', 'NDCG@10': '0.0578', 'HIT@20': '0.1298', 'NDCG@20': '0.0663'}

Please train the model using the Python script main.py.
You can run the following command to train the model on Beauty datasets:
python main.py --data_name Beauty --rec_weight 1. --lambda_0 0.3 --beta_0 0.1 --f_neg --intent_num 256
or
You can use the training scripts in the ./src/scrips folder to train the model
bash beauty.sh
bash ml-1m.sh
bash sports.sh
bash toys.sh
- Transformer and training pipeline are implemented based on CoSeRec and ICLRec. Thanks them for providing efficient implementation.
