Data preparation

Listening events

Download the dataset from Zenodo. Then run the DatasetCreation notebook. This will

• filter the [20-02-2020 -- 19-03-2020] month of the dataset
• remove users that listened to more tracks than 99% of the users
• apply 10 core filtering
• perform a 60-20-20 temporal split for each user
• create the dataset needed for training BPR, MultVAE, and GRU4Rec

Run
