Evaluation of Out-of-Distribution detection performance using CIFAR-100 as the in-distribution dataset and ImageNet-C as the out-of-distribution dataset, measured by AUROC, TNR at 95% TPR, and Detection 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 | OOD Detection |
| Dataset (including any stated split) | CIFAR-100 IND / Imagenet C OOD |
| Metric | AUROC |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 2 of 2 |
| 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/ood-detection-on-cifar-100-ind-vs-imagenet-c-ood.md?metric=AUROC>): Higher is better; unit: SCALAR.

- [TNR at TPR 95%](<https://www.sota2.com/research/sota/ood-detection-on-cifar-100-ind-vs-imagenet-c-ood.md?metric=TNR%20at%20TPR%2095%25>): Higher is better; unit: SCALAR.

- [Detection Accuracy](<https://www.sota2.com/research/sota/ood-detection-on-cifar-100-ind-vs-imagenet-c-ood.md?metric=Detection%20Accuracy>): Higher is better; unit: SCALAR.
