# Classification on ImageNet-100 (50% Seen/50% Novel Split)

Source: [Classification on ImageNet-100 (50% Seen/50% Novel Split)](<https://www.sota2.com/research/sota/classification-on-imagenet-100-50-percent-seen-50-percent-novel-split>)

Evaluation of standard Classification performance on a specific split of ImageNet-100, where 50% of classes are designated as seen and 50% as novel. Results are reported separately for seen, novel, and all classes.

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 | Classification |
| Dataset (including any stated split) | ImageNet-100 50% seen 50% novel |
| Metric | Accuracy (Seen) |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 7 of 7 |
| 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 (Seen)](<https://www.sota2.com/research/sota/classification-on-imagenet-100-50-percent-seen-50-percent-novel-split.md?metric=Accuracy%20(Seen)>): Higher is better; unit: PERCENT.

- [Accuracy (Novel)](<https://www.sota2.com/research/sota/classification-on-imagenet-100-50-percent-seen-50-percent-novel-split.md?metric=Accuracy%20(Novel)>): Higher is better; unit: PERCENT.

- [Accuracy (All)](<https://www.sota2.com/research/sota/classification-on-imagenet-100-50-percent-seen-50-percent-novel-split.md?metric=Accuracy%20(All)>): Higher is better; unit: PERCENT.
