Evaluation of Unsupervised Image Classification performance on the validation split of the Nonliving26 BREEDS dataset, reporting metrics such as Normalized Mutual Information (NMI), Adjusted Mutual Information (AMI), Adjusted Rand Index (ARI), and Accuracy (ACC).

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 | Unsupervised Image Classification |
| Dataset (including any stated split) | Nonliving26 BREEDS (val) |
| Metric | NMI |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 8 of 8 |
| 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/unsupervised-image-classification-on-nonliving26-breeds-val.md?metric=NMI>): Higher is better; unit: PERCENT.

- [AMI](<https://www.sota2.com/research/sota/unsupervised-image-classification-on-nonliving26-breeds-val.md?metric=AMI>): Higher is better; unit: PERCENT.

- [ARI](<https://www.sota2.com/research/sota/unsupervised-image-classification-on-nonliving26-breeds-val.md?metric=ARI>): Higher is better; unit: PERCENT.

- [ACC](<https://www.sota2.com/research/sota/unsupervised-image-classification-on-nonliving26-breeds-val.md?metric=ACC>): Higher is better; unit: PERCENT.
