Title:
FEDERATED LEARNING METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/103291
Kind Code:
A1
Abstract:
Provided in the present application are a federated learning method and a communication apparatus. The federated learning method comprises: an access network device receiving cumulative dual variable change parameters of a task b, which are sent by a plurality of terminal devices; the access network device determining a dual variable change parameter mean value of the task b on the basis of the cumulative dual variable change parameters of the task b, which are sent by the plurality of terminal devices; the access network device determining updated model parameters of the task b on the basis of the dual variable change parameter mean value of the task b; the access network device sending the updated model parameters of the task b to a server; the access network device receiving updated multi-task constraint parameters, which are sent by the server; and the access network device sending the updated model parameters of the task b and the updated multi-task constraint parameters to the plurality of terminal devices. On the basis of the method of the present application, multi-task federated learning and hierarchical federated learning can be combined, such that the calculation difficulty of multi-task federated learning is reduced while the number of tasks is reduced.
