Evaluation of Object Detection performance on the COCO 2017 dataset, specifically restricted to the 80-40 category setting on the test split, using H, APr, and APf 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 | Object Detection |
| Dataset (including any stated split) | COCO 80-40 setting 2017 (test) |
| Metric | APr |
| 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

- [APr](<https://www.sota2.com/research/sota/object-detection-on-coco-80-40-setting-2017-test.md?metric=APr>): Higher is better; unit: PERCENT.

- [H Score](<https://www.sota2.com/research/sota/object-detection-on-coco-80-40-setting-2017-test.md?metric=H%20Score>): Higher is better; unit: SCALAR.

- [APf](<https://www.sota2.com/research/sota/object-detection-on-coco-80-40-setting-2017-test.md?metric=APf>): Higher is better; unit: PERCENT.
