This is the code for the TKDE 2022 Paper: Dynamic Graph Neural Networks for Sequential Recommendation.

Usage

Generate data

You need to run the file new_data.py to generate the data format needed for our model. The detailed commands can be found in load_{dataset}.sh

You need to run the file generate_neg.py to generate data to speed up the test. You can set the data set in the file.

Training and Testing

Then you can run the file new_main.py to train and test our model. The detailed commands can be found in {dataset}.sh
