New benchmark 'Lethe' tests federated unlearning for medical imaging

Researchers have introduced Lethe, a new benchmark designed to evaluate federated unlearning methods specifically for medical imaging applications. Existing unlearning techniques, primarily tested on natural images, may not effectively transfer to the unique characteristics of clinical data. Lethe assesses twelve different methods across eight task families, including classification, segmentation, and vision-language question answering, at varying levels of forgetting granularity. The benchmark's findings indicate that the difficulty of the unlearning request, rather than the method itself, is the primary differentiator, with hard removals being the only ones that significantly separate method performance.

    Lethe: How Hard Is It to Forget? A Benchmark for Federated Unlearning in Medical Imaging

    arXiv:2608.01094v1 Announce Type: new Abstract: Federated learning enables medical-imaging models to be trained across hospitals, and privacy law, most explicitly the GDPR ``right to be forgotten'', turns removing a hospital's, a class's, or a patient's influence from such a mode…
