Evaluation of Anomaly Detection performance on the test split of the Metal\_nut dataset, reporting scores for specific defect types (Bent, Color, Flip, Scratch) and the overall Mean.

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 | Anomaly Detection |
| Dataset (including any stated split) | Metal\_nut (test) |
| Metric | Bent Score |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 3 of 3 |
| 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

- [Bent Score](<https://www.sota2.com/research/sota/anomaly-detection-on-metal_nut-test.md?metric=Bent%20Score>): Higher is better; unit: PERCENT.

- [Color Score](<https://www.sota2.com/research/sota/anomaly-detection-on-metal_nut-test.md?metric=Color%20Score>): Higher is better; unit: PERCENT.

- [Flip Score](<https://www.sota2.com/research/sota/anomaly-detection-on-metal_nut-test.md?metric=Flip%20Score>): Higher is better; unit: PERCENT.

- [Scratch Score](<https://www.sota2.com/research/sota/anomaly-detection-on-metal_nut-test.md?metric=Scratch%20Score>): Higher is better; unit: PERCENT.

- [Mean Score](<https://www.sota2.com/research/sota/anomaly-detection-on-metal_nut-test.md?metric=Mean%20Score>): Higher is better; unit: PERCENT.
