Evaluation of Domain Generalization performance on the Out-of-Distribution (OOD) test split of the PACS dataset, reporting domain-specific accuracies and the average.

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 | Domain Generalization |
| Dataset (including any stated split) | PACS OOD (test) |
| Metric | Average Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 33 of 33 |
| 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

- [Average Accuracy](<https://www.sota2.com/research/sota/domain-generalization-on-pacs-ood-test.md?metric=Average%20Accuracy>): Higher is better; unit: PERCENT.

- [Accuracy (Domain A)](<https://www.sota2.com/research/sota/domain-generalization-on-pacs-ood-test.md?metric=Accuracy%20(Domain%20A)>): Higher is better; unit: PERCENT.

- [Accuracy (Domain C)](<https://www.sota2.com/research/sota/domain-generalization-on-pacs-ood-test.md?metric=Accuracy%20(Domain%20C)>): Higher is better; unit: PERCENT.

- [Accuracy (Domain P)](<https://www.sota2.com/research/sota/domain-generalization-on-pacs-ood-test.md?metric=Accuracy%20(Domain%20P)>): Higher is better; unit: PERCENT.

- [Accuracy (Domain S)](<https://www.sota2.com/research/sota/domain-generalization-on-pacs-ood-test.md?metric=Accuracy%20(Domain%20S)>): Higher is better; unit: PERCENT.

- [Accuracy Increase](<https://www.sota2.com/research/sota/domain-generalization-on-pacs-ood-test.md?metric=Accuracy%20Increase>): Higher is better; unit: PERCENT.

- [Improvement (%)](<https://www.sota2.com/research/sota/domain-generalization-on-pacs-ood-test.md?metric=Improvement%20(%25)>): Higher is better; unit: PERCENT.
