Evaluation of next-item prediction performance on a proprietary dataset covering three years of music and podcast streaming behavior, measured by metrics related to drift recovery.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Next-item prediction |
| Dataset (including any stated split) | Proprietary music and podcast streaming dataset (3-year evaluation horizon) |
| Metric | NDCG@50 Drift Recovery |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.
