Federated learning optimization algorithm based on incentive mechanism
Published 2023-05-01“…Federated learning optimization algorithm based on incentive mechanism was proposed to address the issues of multiple iterations, long training time and low efficiency in the training process of federated learning.Firstly, the reputation value related to time and model loss was designed.Based on the reputation value, an incentive mechanism was designed to encourage clients with high-quality data to join the training.Secondly, the auction mechanism was designed based on the auction theory.By auctioning local training tasks to the fog node, the client entrusted the high-performance fog node to train local data, so as to improve the efficiency of local training and solve the problem of performance imbalance between clients.Finally, the global gradient aggregation strategy was designed to increase the weight of high-precision local gradient in the global gradient and eliminate malicious clients, so as to reduce the number of model training.…”

Performance analysis and optimization of cooperative spectrum sensing with relay
Published 2013-09-01“…An object based cooperative spectrum sensing scheme with relay was proposed,and the fact that the channel condition from SU to SR has an important influence to system performance was proved.In view of this,an optimized cooperative spectrum sensing scheme with best relay(optimized BRCSS) was proposed,in which the best secondary relay was selected by considering both the channel condition from SU to SR and SR to FC.Finally,an adaptive cooperative spectrum sensing scheme with best relay (A-BRCSS) was proposed further to save the system expense considering more practical application occasion,where,SU could adaptively decide whether the relay’s cooperation was needed by its reporting channel condition.Both analysis and simulation results show that,the better sensing performance can be achieved by the optimized BRCSS scheme compared with the tradit l cooperative spectrum sensing scheme with best relay.The nearly best sensing performance can be obtained by the proposed A-BRCSS scheme.…”
