Evaluation of Pain Classification performance on the Older Adult Control dataset, measured using temporal F1 scores (frame, 1sec, 5sec, 20sec).

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 | Pain Classification |
| Dataset (including any stated split) | Older Adult Control |
| Metric | F1 (frame) |
| Unit | PERCENT |
| 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

- [F1 (frame)](<https://www.sota2.com/research/sota/pain-classification-on-older-adult-control.md?metric=F1%20(frame)>): Higher is better; unit: PERCENT.

- [F1 (1sec)](<https://www.sota2.com/research/sota/pain-classification-on-older-adult-control.md?metric=F1%20(1sec)>): Higher is better; unit: PERCENT.

- [F1 (5sec)](<https://www.sota2.com/research/sota/pain-classification-on-older-adult-control.md?metric=F1%20(5sec)>): Higher is better; unit: PERCENT.

- [F1 (20sec)](<https://www.sota2.com/research/sota/pain-classification-on-older-adult-control.md?metric=F1%20(20sec)>): Higher is better; unit: PERCENT.
