LFM User Groups Implicit Feedback

This is a variant of the popular LFM User Groups dataset [1] used in the paper "The Impact of Differential Privacy on Recommendation Accuracy and Popularity Bias" [2]. Each user's listening events for an artist are scaled to values between 1 and 5 (the user's min. value being 1 and the max. value being 5). Then, scores above the mean are considered positive feedback whereas scores below the mean are considered as negative feedback. This dataset only includes the positive feedback data. The source-code for generating this dataset is available in our repository [3].
