Evaluation of Class Discovery performance on the ImageNet-100 dataset, reporting metrics for All, Old, and New categories.

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 | Class Discovery |
| Dataset (including any stated split) | ImageNet 100 |
| Metric | Accuracy (All) |
| Unit | PERCENT |
| 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

- [Accuracy (All)](<https://www.sota2.com/research/sota/class-discovery-on-imagenet-100.md?metric=Accuracy%20(All)>): Higher is better; unit: PERCENT.

- [Accuracy (Old)](<https://www.sota2.com/research/sota/class-discovery-on-imagenet-100.md?metric=Accuracy%20(Old)>): Higher is better; unit: PERCENT.

- [Accuracy (New)](<https://www.sota2.com/research/sota/class-discovery-on-imagenet-100.md?metric=Accuracy%20(New)>): Higher is better; unit: PERCENT.
