New federated learning method optimizes AUC for disease prediction models

Researchers have developed a new method called geographically regularized AUC-maximizing personalized federated learning (GrAUC-PFL) to address challenges in building accurate diagnostic and risk-prediction models for infectious diseases. This approach allows healthcare institutions to train personalized models without sharing patient-level data, directly optimizing for Area Under the Curve (AUC) performance. GrAUC-PFL uses graph-based regularization to encourage similarity among geographically proximate institutions, improving model performance especially when their data characteristics align. AI

IMPACT This method could improve the accuracy and privacy of disease prediction models across healthcare institutions.
