Continuous-Time User Preference Modelling for Temporal Sets Prediction

The description of "Continuous-Time User Preference Modelling for Temporal Sets Prediction" is available here.

Original data:

The original data could be downloaded from here. You can download the data and then put the data files in the ./original_data folder.

To run the code:

1. run ./preprocess_data/preprocess_data_{dataset_name}.py to preprocess the original data, where dataset_name can be JingDong, DC, TaFeng and TaoBao. We also provide the preprocessed datasets at here, which should be put in the ./dataset folder.

2. run ./train/train_CTTSP.py to train the model on different datasets using the configuration in ./utils/config.json.

3. run ./evaluate/evaluate_CTTSP.py to evaluate the model. Please make sure the config in evaluate_CTTSP.py keeps identical to that in the model training process.

Environments:

• PyTorch 1.8.1
• tqdm
• numpy
• pandas

Hyperparameter settings:

Hyperparameters can be found in ./utils/config.json file, and you can adjust them when training the model on different datasets.
