arXiv:2605.24545v1 Announce Type: new Abstract: Federated learning (FL) increasingly needs machine unlearning to comply with privacy regulations. However, existing federated unlearning approaches may overlook the overlapping information between the unlearning and remaining data, leading to ineffective unlearning and unfairness between clients. In this work, we revisit federated unlearning through the lens of memorization. We argue that unlearning should mainly remove the unique memorized information attributable to the data to be forgotten, while preserving overlapping patterns that are also s
The increasing adoption of federated learning (FL) amidst tightening privacy regulations makes effective machine unlearning a critical and timely research area.
This research addresses a core challenge in privacy-preserving AI, directly impacting the deployability and ethical governance of FL systems in sensitive domains.
A refined understanding of federated unlearning that prioritizes removing unique memorized data while preserving common patterns could lead to more efficient and fairer unlearning protocols.
