FuGuard: Client-Level Federated Unlearning via Generative Surrogates and Optimal Transport.
FuGuard is proposed, a dual-strategy federated unlearning framework, designed for efficient and ideal client-level data removal that combines the generative surrogate, which approximates the contribution of the target client, with optimal transport regularization that softly constrains model parameter drift during unlearning.
