Evaluation of Semantic Segmentation performance on the val test split of the BIG 1.0 dataset, reporting metrics like IoU and mBA.

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) | BIG 1.0 (val test) |
| Metric | IoU |
| 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

- [IoU](<https://www.sota2.com/research/sota/semantic-segmentation-on-big-1-0-val-test.md?metric=IoU>): Higher is better; unit: PERCENT.

- [mBA](<https://www.sota2.com/research/sota/semantic-segmentation-on-big-1-0-val-test.md?metric=mBA>): Higher is better; unit: PERCENT.
