FedCoRe: Target-Adaptive Completion for Missing Modalities in Healthcare Federated Learning

Holger R. Roth, Ziyue Xu, Peter Cnudde

Federated multimodal models often assume every site has every modality, although hospitals differ in access to EHRs, chest radiographs, and ECGs. We study this setting on a MIMIC-d…
