Evaluation of Image Classification performance on the test split of the SO(2) discretized version of Rotated MNIST, reporting KNN Accuracy.

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 | Image Classification |
| Dataset (including any stated split) | Rotated MNIST SO(2) discretized (test) |
| Metric | KNN Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 6 of 6 |
| 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

- [KNN Accuracy](<https://www.sota2.com/research/sota/image-classification-on-rotated-mnist-so-2-discretized-test.md?metric=KNN%20Accuracy>): Higher is better; unit: PERCENT.
