Evaluation of Few-Shot Classification performance on the COCO-20i dataset configured specifically for 2-way, 1-shot learning, typically measured using Error Rate (ER).

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 | Few-Shot Classification |
| Dataset (including any stated split) | COCO-20i 2-way 1-shot |
| Metric | Error Rate (%) |
| Unit | PERCENT |
| Direction | Lower 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.

## Metrics

- [Error Rate (%)](<https://www.sota2.com/research/sota/few-shot-classification-on-coco-20i-2-way-1-shot.md?metric=Error%20Rate%20(%25)>): Lower is better; unit: PERCENT.
