Evaluation of Multi-object discovery performance on the 20k subset of the MS COCO dataset, measured using AP50, AP75, and AP metrics.

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 | Multi-object discovery |
| Dataset (including any stated split) | MS COCO (20k) |
| Metric | AP50 |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 6 of 6 |
| 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

- [AP50](<https://www.sota2.com/research/sota/multi-object-discovery-on-ms-coco-20k.md?metric=AP50>): Higher is better; unit: PERCENT.

- [AP75](<https://www.sota2.com/research/sota/multi-object-discovery-on-ms-coco-20k.md?metric=AP75>): Higher is better; unit: PERCENT.

- [AP](<https://www.sota2.com/research/sota/multi-object-discovery-on-ms-coco-20k.md?metric=AP>): Higher is better; unit: PERCENT.
