Research on federated learning approach based on local differential privacy by Haiyan KANG, Yuanrui JI

“…As a type of collaborative machine learning framework, federated learning is capable of preserving private data from participants while training the data into useful models.Nevertheless, from a viewpoint of information theory, it is still vulnerable for a curious server to infer private information from the shared models uploaded by participants.To solve the inference attack problem in federated learning training, a local differential privacy federated learning (LDP-FL) approach was proposed.Firstly, to ensure the federated model training process was protected from inference attacks, a local differential privacy mechanism was designed for transmission of parameters in federated learning.Secondly, a performance loss constraint mechanism for federated learning was proposed and designed to reduce the performance loss of local differential privacy federated model by optimizing the constraint range of the loss function.Finally, the effectiveness of proposed LDP-FL approach was verified by comparative experiments on MNIST and Fashion MNIST datasets.…”

Hurst and priority adaptive RED combined with dynamic scheduling algorithm based on AOS by Yu-xia BIE, Cheng-sheng PAN, Hai-yan LIU, Yan-chun WANG

“…In order to efficiently transmit different types of high-capacity and burst data,based on virtual channel multiplexing technology on advanced orbiting systems(AOS),a Hurst and priority adaptive random early detection(RED) combined with dynamic scheduling algorithm named HPRED-DS was proposed.In queue management state,the algorithm designed an adaptive two-level packet dropping strategy based on Hurst parameter and priority.In virtual channel scheduling state,a VIP,synchronous and asynchronous mixed virtual channels scheduling mode was designed.Meanwhile,the algorithm efficiently combined queue management and virtual channel scheduling.Experimental results show that on the basis of maintaining high treatment efficiency and throughput,the algorithm stabilizes queue length,reduces delay and delay jitter,can meet various services’transmitting requirement.…”

Low complexity hybrid precoding method in mmWave massive MIMO system by Jianwei XIANG, Xiulan YU, Xiaorong JING

“…A low-complexity hybrid precoding method was proposed to design the hybrid precoding for mmWave massive MIMO system.Firstly,an initial radio frequency(RF)precoding matrix was constructed based on the singular value decomposition.Then an updated RF matrix was constructed by placing the vector which was constructed by the biggest left singular vectors of the residual matrix onto the last column of the initial RF matrix.By multiple iterations,the resultant RF precoding matrix can be obtained and the digital precoding matrix was designed based on the least square criterion.Theoretical analysis and simulation results show that the proposed algorithm greatly outperforms the hybrid precoding method based on orthogonal matching pursuit(OMP)algorithm with much reduced computational complexity.Additionally,the proposed hybrid precoding method has almost the same performance as the full digital precoding method when the number of data stream is relatively less.…”
