Abstract:
Provided in the embodiments of the present description are a method and apparatus for jointly updating service models on the basis of privacy protection. The method comprises: during an iteration process, a service party providing, to each data party, global model parameters, and correspondences between the data party and N parameter groups which are obtained by means of dividing the global model parameters; each data party updating a local service model by using the global model parameters, and further updating the updated local service model on the basis of local service data, so as to upload, to the service party, model parameters, in the new service model, of a parameter group corresponding to the data party; and then the service party successively fusing the received parameter groups, so as to update the global model parameters. During the process, the communication pressure between data parties and a service party can be reduced, thereby avoiding communication blockage, and facilitating the improvement of the overall training efficiency of federated learning.
