Evaluation of Novel Class Discovery performance on the SemanticKITTI dataset using the specific 'KITTI-4^3' configuration. Metrics include mean IoU (mIoU) for novel, base, and all classes, alongside detailed per-class IoU scores for 3D scene elements.

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 | Novel Class Discovery |
| Dataset (including any stated split) | SemanticKITTI KITTI-4^3 |
| Metric | IoU (bike) |
| Unit | PERCENT |
| 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.
