Evaluation of Underwater Acoustic Target Recognition performance on the ShipsEar dataset, reporting OA, AA, Kappa, and F1 scores.

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 | Underwater Acoustic Target Recognition |
| Dataset (including any stated split) | ShipsEar |
| Metric | OA |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 9 of 9 |
| 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

- [OA](<https://www.sota2.com/research/sota/underwater-acoustic-target-recognition-on-shipsear.md?metric=OA>): Higher is better; unit: PERCENT.

- [AA](<https://www.sota2.com/research/sota/underwater-acoustic-target-recognition-on-shipsear.md?metric=AA>): Higher is better; unit: PERCENT.

- [Kappa](<https://www.sota2.com/research/sota/underwater-acoustic-target-recognition-on-shipsear.md?metric=Kappa>): Higher is better; unit: PERCENT.

- [F1 Score](<https://www.sota2.com/research/sota/underwater-acoustic-target-recognition-on-shipsear.md?metric=F1%20Score>): Higher is better; unit: PERCENT.
