Evaluation of 1-way few-shot segmentation performance on the validation split of the MS COCO dataset, measured using IoU metrics.

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 | 1-way few-shot segmentation |
| Dataset (including any stated split) | MS COCO (val) |
| Metric | Binary IoU |
| 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

- [Binary IoU](<https://www.sota2.com/research/sota/1-way-few-shot-segmentation-on-ms-coco-val.md?metric=Binary%20IoU>): Higher is better; unit: PERCENT.

- [mIoU](<https://www.sota2.com/research/sota/1-way-few-shot-segmentation-on-ms-coco-val.md?metric=mIoU>): Higher is better; unit: PERCENT.
