This is the repository for paper: ContrastVAE: Contrastive Variational AutoEncoder for Sequential Recommendation

--variational_dropout : using the variational augmentation

--latent_contrastive_learning: using the model augmentation

--latent_data_augmentation: using the data augmentation

--VAandDA: using both variational augmentation and data augmentation

without any above version control: the model is the vanilla attentive variational autoencoder
