New framework optimizes federated learning for healthcare centers

Researchers have developed Adaptive Bayesian Partner Selection (ABPS), a peer-to-peer framework designed to improve federated learning in healthcare settings. This approach addresses challenges like data heterogeneity and concept drift by enabling clinical centers to intelligently select collaborators based on predicted utility. ABPS uses a Bayesian approach with Shapley values and an Upper Confidence Bound criterion to manage communication costs and avoid negative transfer, even allowing for intentional isolation when beneficial. Experiments on in-hospital mortality prediction using MIMIC-IV data demonstrated that ABPS-X could match strong federated baselines with significantly reduced communication overhead and variability.
