MODEL TRAINING METHOD AND APPARATUS, AND COMMUNICATION DEVICE

This application relates to the field of communication technologies, and discloses a model training method and apparatus and a communication device. The model training method in embodiments of this application includes: A first network element sends a federated model training request message to at least one second network element when performing a federated model training process corresponding to a model training task, where the at least one second network element is a network element participating in the federated model training process. The first network element receives first information sent by the at least one second network element, where the first information includes at least first model training intermediate data, the first model training intermediate data corresponds to samples used for federated model training in the second network element, and the samples used for federated model training in the second network elements are the same but sample features are different. The first network element performs model training based on the first model training intermediate data reported by the at least one second network element to obtain a target model and/or second model training intermediate data.
