Evaluation of Open-Set Recognition performance on the test split of the ImageNet 1k dataset, reporting C-F1 score.

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) | ImageNet 1k (test) |
| Metric | C-F1 |
| 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

- [C-F1](<https://www.sota2.com/research/sota/open-set-recognition-on-imagenet-1k-test.md?metric=C-F1>): Higher is better; unit: PERCENT.
