Evaluation of Open-Set Recognition performance on the CUB dataset, reporting KRR and HC-FKAR.

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 | Open-Set Recognition |
| Dataset (including any stated split) | CUB |
| Metric | KRR |
| Unit | PERCENT |
| Direction | Lower is better |
| Results loaded | 10 of 10 |
| 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

- [KRR](<https://www.sota2.com/research/sota/open-set-recognition-on-cub.md?metric=KRR>): Lower is better; unit: PERCENT.

- [HC-FKAR](<https://www.sota2.com/research/sota/open-set-recognition-on-cub.md?metric=HC-FKAR>): Higher is better; unit: PERCENT.

- [Known Accuracy](<https://www.sota2.com/research/sota/open-set-recognition-on-cub.md?metric=Known%20Accuracy>): Higher is better; unit: PERCENT.
