Evaluation of Machine Unlearning effectiveness on the CASIA-WebFace Forget 500 Class dataset, reporting utility and unlearning-specific metrics.

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 | Machine Unlearning |
| Dataset (including any stated split) | CASIA-WebFace Forget 500 Class |
| Metric | Accuracy (Forget) |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| 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 (Forget)](<https://www.sota2.com/research/sota/machine-unlearning-on-casia-webface-forget-500-class.md?metric=Accuracy%20(Forget)>): Higher is better; unit: PERCENT.

- [Accuracy (Retain)](<https://www.sota2.com/research/sota/machine-unlearning-on-casia-webface-forget-500-class.md?metric=Accuracy%20(Retain)>): Higher is better; unit: PERCENT.

- [Overlap Utility (epsilon)](<https://www.sota2.com/research/sota/machine-unlearning-on-casia-webface-forget-500-class.md?metric=Overlap%20Utility%20(epsilon)>): Higher is better; unit: PERCENT.

- [Prototype Accuracy (Forget)](<https://www.sota2.com/research/sota/machine-unlearning-on-casia-webface-forget-500-class.md?metric=Prototype%20Accuracy%20(Forget)>): Higher is better; unit: PERCENT.

- [Accuracy\* (Retain)](<https://www.sota2.com/research/sota/machine-unlearning-on-casia-webface-forget-500-class.md?metric=Accuracy*%20(Retain)>): Higher is better; unit: PERCENT.
