CMST-FL: Cross-Missingness Stable Trust with Evidence-Guided Preprocessing for Federated Healthcare Signal Imputation

Missing physiological samples create preprocessing uncertainty and uneven client reliability in federated learning. This study proposes Cross-Missingness Stable Trust federated learning (CMST-FL), a two-stage framework that selects an imputer using development patients and then weights local updates from their marginal...

AI-Based Preprocessing and R-Squared Weighted Federated Aggregation for Robust Healthcare Signal Imputation

This work presents an AI based preprocessing framework that combines advanced imputation methods, including K Nearest Neighbors (KNN), Autoencoder reconstruction, and Generative Adversarial Networks (GAN), with classical baselines such as mean and median imputation to provide robust convergence and stability in federat...
