Evaluation of Image Classification performance on the test split of the CIFAR-100 dataset configured with a 50x Long-Tailed imbalance ratio, measured using AUCOC and 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) | CIFAR100 Long-Tailed (imbalance ratio 50) (test) |
| Metric | AUROC |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 11 of 11 |
| 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

- [AUROC](<https://www.sota2.com/research/sota/image-classification-on-cifar100-long-tailed-imbalance-ratio-50-test.md?metric=AUROC>): Higher is better; unit: PERCENT.

- [Accuracy](<https://www.sota2.com/research/sota/image-classification-on-cifar100-long-tailed-imbalance-ratio-50-test.md?metric=Accuracy>): Higher is better; unit: PERCENT.
