Evaluation of Outlier Detection performance on the historical version of the vowels dataset, measured using AUROC and AUPRC.

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 | Outlier Detection |
| Dataset (including any stated split) | vowels (historical) |
| Metric | AUROC |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 17 of 17 |
| 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

- [AUROC](<https://www.sota2.com/research/sota/outlier-detection-on-vowels-historical.md?metric=AUROC>): Higher is better; unit: SCALAR.

- [AUPRC](<https://www.sota2.com/research/sota/outlier-detection-on-vowels-historical.md?metric=AUPRC>): Higher is better; unit: SCALAR.
