Evaluation of Human-Object Interaction Recognition performance on the specialized 'Systematic-hard' subset/split of the HICO dataset, reporting metrics related to full and unseen classes.

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 | Human-Object Interaction Recognition |
| Dataset (including any stated split) | HICO (Systematic-hard) |
| Metric | mAP (Full Classes) |
| 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

- [mAP (Full Classes)](<https://www.sota2.com/research/sota/human-object-interaction-recognition-on-hico-systematic-hard.md?metric=mAP%20(Full%20Classes)>): Higher is better; unit: PERCENT.

- [mAP (Unseen Classes)](<https://www.sota2.com/research/sota/human-object-interaction-recognition-on-hico-systematic-hard.md?metric=mAP%20(Unseen%20Classes)>): Higher is better; unit: PERCENT.
