Evaluation of k-means clustering performance on the MNIST8M k=10 dataset, measured using Normalized Mutual Information (NMI).

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 | k-means clustering |
| Dataset (including any stated split) | MNIST8M k=10 |
| Metric | NMI |
| 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.

## Metrics

- [NMI](<https://www.sota2.com/research/sota/k-means-clustering-on-mnist8m-k-10.md?metric=NMI>): Higher is better; unit: SCALAR.
