Evaluation of model performance on binary known/unknown decision tasks using the Hard variant of the ImageNet dataset, typically measured using Average Precision (AP).

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 | Binary known/unknown decision |
| Dataset (including any stated split) | ImageNet Hard |
| Metric | AP |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 2 of 2 |
| 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

- [AP](<https://www.sota2.com/research/sota/binary-known-unknown-decision-on-imagenet-hard.md?metric=AP>): Higher is better; unit: PERCENT.
