# KuaiRec

Parquet republication of [KuaiRec](https://kuairec.com/) for the Lizard benchmark.
This is not the official repository. The files were converted from the Zenodo release without adding a train/test cut.

The authors use the big interaction matrix for training and the fully observed small matrix for evaluation. Those are separate released tables, so they are separate configs here. Each config has one split, `train`, containing every row of that table.

Field definitions are on the homepage. CSV text is preserved as `VARCHAR`. Typed ids and timestamps, `source_row`, `dataset_source`, and `synthetic` are added. `source_row` is the 1-based source line number, assigned before sorting. No rolling history or label was derived.
