Evaluation of On-the-Fly Category Discovery performance on the test split of the Stanford Cars dataset, specifically using the C=196 class configuration. Metrics include class count and accuracy 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 | On-the-Fly Category Discovery |
| Dataset (including any stated split) | Stanford Cars C=196 (test) |
| Metric | Number of Classes Found |
| Unit | SCALAR |
| 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

- [Number of Classes Found](<https://www.sota2.com/research/sota/on-the-fly-category-discovery-on-stanford-cars-c-196-test.md?metric=Number%20of%20Classes%20Found>): Higher is better; unit: SCALAR.

- [Accuracy (All)](<https://www.sota2.com/research/sota/on-the-fly-category-discovery-on-stanford-cars-c-196-test.md?metric=Accuracy%20(All)>): Higher is better; unit: PERCENT.

- [Accuracy (Old)](<https://www.sota2.com/research/sota/on-the-fly-category-discovery-on-stanford-cars-c-196-test.md?metric=Accuracy%20(Old)>): Higher is better; unit: PERCENT.

- [Accuracy (New)](<https://www.sota2.com/research/sota/on-the-fly-category-discovery-on-stanford-cars-c-196-test.md?metric=Accuracy%20(New)>): Higher is better; unit: PERCENT.
