Evaluation of Semantic Segmentation performance on the A-847 dataset, specifically reporting Mean Intersection over Union (mIoU) metrics segregated by seen and unseen categories or domains.

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 | Semantic Segmentation |
| Dataset (including any stated split) | A-847 |
| Metric | mIoU (Seen) |
| 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

- [mIoU (Seen)](<https://www.sota2.com/research/sota/semantic-segmentation-on-a-847-seen-unseen-evaluation.md?metric=mIoU%20(Seen)>): Higher is better; unit: PERCENT.

- [mIoU (Unseen)](<https://www.sota2.com/research/sota/semantic-segmentation-on-a-847-seen-unseen-evaluation.md?metric=mIoU%20(Unseen)>): Higher is better; unit: PERCENT.
