Researchers have introduced COSMOS, a novel framework designed to enhance personalized federated learning in heterogeneous environments. This model-agnostic approach utilizes pseudo-label communication, allowing clients to train local models and predict on public data. The server then clusters clients based on prediction similarity, trains cluster-specific models, and distills them back to the clients. Theoretical analysis suggests this method can lead to exponential personalization risk contraction, outperforming existing model-agnostic federated learning baselines and competing with state-of-the-art personalized federated learning techniques.
