Evaluation of Image Clustering performance on the full EMNIST dataset, measured by ACC, NMI, and ARI.

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 Clustering |
| Dataset (including any stated split) | EMNIST (full) |
| Metric | ACC |
| Unit | PERCENT |
| 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.

## Metrics

- [ACC](<https://www.sota2.com/research/sota/image-clustering-on-emnist-full.md?metric=ACC>): Higher is better; unit: PERCENT.

- [NMI](<https://www.sota2.com/research/sota/image-clustering-on-emnist-full.md?metric=NMI>): Higher is better; unit: PERCENT.

- [ARI](<https://www.sota2.com/research/sota/image-clustering-on-emnist-full.md?metric=ARI>): Higher is better; unit: PERCENT.
