Evaluation of Semantic Image Synthesis performance on the outdoor subset of the ADE20K validation set, measured using FID and mIoU.

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 Image Synthesis |
| Dataset (including any stated split) | ADE-outd. (val) |
| Metric | FID |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 7 of 7 |
| 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

- [FID](<https://www.sota2.com/research/sota/semantic-image-synthesis-on-ade20k_outdoor-val.md?metric=FID>): Lower is better; unit: SCALAR.

- [mIoU](<https://www.sota2.com/research/sota/semantic-image-synthesis-on-ade20k_outdoor-val.md?metric=mIoU>): Higher is better; unit: PERCENT.
