Diffusion Augmentation for Sequential Recommendation

This is the implementation of the paper "Diffusion Augmentation for Sequential Recommendation".

You can implement our model according to the following steps:

The handle dataset should be put into ./data/<dataset>/handled/
Install the necessary packages. Run the command:
```
pip install -r requirements.txt
```
To get train the DiffuASR and augment the corresponding dataset, please run the command:
```
bash ./experiments/diffusion.bash
```
Finally, you can run the following bash to test the augmention performance for Bert4Rec:
```
bash ./experiments/bert4rec.bash
```
