Evaluation of unsupervised clustering performance on the ISOLET dataset, measured using Adjusted Rand Index (ARI) and 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 | Clustering |
| Dataset (including any stated split) | ISOLET |
| Metric | ARI |
| Unit | SCALAR |
| 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

- [ARI](<https://www.sota2.com/research/sota/clustering-on-isolet-ari-nmi.md?metric=ARI>): Higher is better; unit: SCALAR.

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