Classification: CPC H  Y | IPC H

Claim 5:
6. The dynamic power control method for resisting multi-user parameter biased aggregation in federated learning according to claim 1, wherein in step (5), after being received, the aggregation value of gradient signs of federated learning training is transmitted back to each user, and each user uses the aggregation value to update a current federated learning system model via gradient descent based on the following equation, namely Formula (XIII):

w(n+1)=w(n)−δv(n)  (XIII),

wherein w(n+1) is the federated learning system model parameter vector of the n+1th communication, δ is the learning rate, w(n) is the federated learning system model parameter vector of the nth communication, and Formula (XIII) is continuously repeated until a predetermined convergence criterion is reached.
