Evaluation of Semantic Segmentation performance on the Fantastic Beasts 20^2 dataset, reporting metrics across specific configurations (20^0, 20^1, 20^2, 20^3) and overall 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 Segmentation |
| Dataset (including any stated split) | Fantastic Beasts 20^2 (20^0, 20^1, 20^2, 20^3) |
| Metric | Score (20^0) |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| 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.
