Evaluation of Action Recognition performance on the Something-Something V2 dataset, reporting specific metrics categorized as Base, Novel, and HM.

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 | Action Recognition |
| Dataset (including any stated split) | SS v2 |
| Metric | Base Score |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 8 of 8 |
| 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

- [Base Score](<https://www.sota2.com/research/sota/action-recognition-on-ss-v2-base-novel-hm-metrics.md?metric=Base%20Score>): Higher is better; unit: SCALAR.

- [Novel Score](<https://www.sota2.com/research/sota/action-recognition-on-ss-v2-base-novel-hm-metrics.md?metric=Novel%20Score>): Higher is better; unit: SCALAR.

- [HM Score](<https://www.sota2.com/research/sota/action-recognition-on-ss-v2-base-novel-hm-metrics.md?metric=HM%20Score>): Higher is better; unit: SCALAR.
