Detailed Description

k-fold cross-validation split for rating prediction

Please note that k-fold cross-validation is not the best/most realistic way of evaluating recommender system algorithms. In particular, chronological splits (RatingsChronologicalSplit) are more realistic.

The dataset must not be modified after the split - this would lead to undefined behavior.
