Evaluation of Classification performance on the A9 dataset using the out-of-sample split, measured using median AUC.

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 | Classification |
| Dataset (including any stated split) | A9 (out-of-sample) |
| Metric | Median AUC |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| 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.

## Metrics

- [Median AUC](<https://www.sota2.com/research/sota/classification-on-a9-out-of-sample.md?metric=Median%20AUC>): Higher is better; unit: PERCENT.
