Evaluation of Spatio-temporal Action Localization performance on the validation split of the AVA-Kinetics dataset, typically measured using Mean Average Precision (mAP).

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 | Spatio-temporal action localization |
| Dataset (including any stated split) | AVA-Kinetics (val) |
| Metric | mAP |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| 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

- [mAP](<https://www.sota2.com/research/sota/spatio-temporal-action-localization-on-ava-kinetics-val.md?metric=mAP>): Higher is better; unit: PERCENT.
