Evaluation of Fine-grained Video Categorization performance on the validation split of the ActivityNet v1.3 dataset, measured using Top-1, Top-3 accuracy, and 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 | Fine-grained Video Categorization |
| Dataset (including any stated split) | ActivityNet v1.3 (val) |
| Metric | mAP |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 32 of 32 |
| 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/fine-grained-video-categorization-on-activitynet-v1-3-val.md?metric=mAP>): Higher is better; unit: PERCENT.

- [Top-1 Accuracy](<https://www.sota2.com/research/sota/fine-grained-video-categorization-on-activitynet-v1-3-val.md?metric=Top-1%20Accuracy>): Higher is better; unit: PERCENT.

- [Top-3 Accuracy](<https://www.sota2.com/research/sota/fine-grained-video-categorization-on-activitynet-v1-3-val.md?metric=Top-3%20Accuracy>): Higher is better; unit: PERCENT.
