- Abstract:
-
Differential privacy is widely used in federated learning to ensure the security of model parameters. However, inappropriate methods for adding noise can limit the further improvement of model accuracy. A federated learning method with adaptive allocation of the privacy budget and calculation of the learning rate (DP–FLAGD) is proposed to address this problem. Through the adaptive allocation of the privacy budget, the right descending direction of the gradient can be identified, and the appropriate learning rate can be calculated to achieve minimal loss. Simultaneously, DP–FLAGD provides different privacy budgets for users with various privacy requirements. Experiments were conducted on two widely used datasets, namely MNIST and CIFAR-10, to evaluate the validity of DP–FLAGD. Experimental results show that the DP–FLAGD scheme can further improve model accuracy while ensuring the safety of model parameters.
