Définition CISMeF : A decentralized approach to training ML models. Models are trained by each site on data that are kept locally, and model updates are sent to a central server, whereby the central server aggregates these updates to improve a global model. This method is designed to preserve data privacy, as raw data remain at the local sites and are not centralized. For example, federated learning can allow hospitals to collaborate on a heart disease prediction model without sharing patient data. The model is sent to be trained locally at each hospital, and only the model updates from each hospital, not raw data, are sent back and aggregated. This way, individual patient information remains localized, addressing privacy concerns while still benefiting from a collectively improved model.; Source: Adapted from: Darzidehkalani, E., Ghasemi-rad, M., & van Ooijen, P.
