Evaluation of video action recognition performance on the UCF open-vocabulary dataset, measured using Base, Novel, and Harmonic mean scores.

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) | UCF open-vocabulary |
| Metric | Base Score |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| 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-ucf-open-vocabulary.md?metric=Base%20Score>): Higher is better; unit: PERCENT.

- [Novel Score](<https://www.sota2.com/research/sota/action-recognition-on-ucf-open-vocabulary.md?metric=Novel%20Score>): Higher is better; unit: PERCENT.

- [Harmonic Mean Score](<https://www.sota2.com/research/sota/action-recognition-on-ucf-open-vocabulary.md?metric=Harmonic%20Mean%20Score>): Higher is better; unit: PERCENT.
