Evaluation of Object Affordance Anticipation performance on the unseen split of the PIAD dataset, measured using AUC, aIOU, and SIM.

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 | Object affordance anticipation |
| Dataset (including any stated split) | PIAD (Unseen) |
| Metric | AUC |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| 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

- [AUC](<https://www.sota2.com/research/sota/object-affordance-anticipation-on-piad-unseen.md?metric=AUC>): Higher is better; unit: PERCENT.

- [aIOU](<https://www.sota2.com/research/sota/object-affordance-anticipation-on-piad-unseen.md?metric=aIOU>): Higher is better; unit: PERCENT.

- [SIM](<https://www.sota2.com/research/sota/object-affordance-anticipation-on-piad-unseen.md?metric=SIM>): Higher is better; unit: SCALAR.
