arXiv:2605.21317v1 Announce Type: new Abstract: The aggregation of conflicting client updates remains a fundamental bottleneck in federated learning (FL) under heterogeneous data distributions. Naive averaging can produce a global update that improves the global objective while conflicting with specific clients, causing degradation for those clients. In this work, we propose CRAFT (Conflict-Resolved Aggregation for Federated Training), a new aggregation framework that treats the global update as a geometric correction problem. We formulate aggregation as finding the update closest to a referen
The proliferation of federated learning applications, particularly in privacy-sensitive domains and across heterogeneous data sources, highlights the urgent need for robust aggregation methods.
Improved federated learning aggregation can enhance the fairness and efficacy of AI models trained on distributed data, reducing data dependency and potentially improving model generalization.
This research suggests a more resilient approach to aggregating diverse client updates in federated learning, addressing a key bottleneck in its performance and broader adoption.
