    High-performance federated continual learning algorithm for heterogeneous streaming data by Hui JIANG, Tianliu HE, Min LIU, Sheng SUN, Yuwei WANG

    Published 2023-05-01
    “…Aiming at the problems of poor model performance and low training efficiency in training streaming data of AI models that provide intelligent services, a high-performance federated continual learning algorithm for heterogeneous streaming data (FCL-HSD) was proposed in the distributed terminal system with privacy data.In order to solve the problem of the current model forgetting old data, a model with dynamically extensible structure was introduced in the local training stage, and an extension audit mechanism was designed to ensure the capability of the AI model to recognize old data at the cost of small storage overhead.Considering the heterogeneity of terminal data, a customized global model strategy based on data distribution similarity was designed at the central server side, and an aggregation-by-block manner was implemented for different modules of the model.The feasibility and effectiveness of the proposed algorithm were verified under various data increment scenarios with different data sets.Experimental results show that, compared with existing works, the proposed algorithm can effectively improve the model performance to classify old data on the premise of ensuring the capability to classify new data.…”

    Performance analysis and re-modeling of secondary users in cognitive radio system by Wei LIN, Yu FU, Qin-yu ZHANG, Ye WANG, Sheng WANG

    Published 2012-11-01
    “…A number of errors in the past Markov model and theoretical analysis were discussed in spectrum access based on cognitive radio network (CRN).To imitate the behav ary user (PU) and secondary user (SU) factually,new models for access strategy were presented.The performance of CRN based on different access strategies were reappraised and compared by using matrix geometric theory and event scheduling of discrete events system simulation.Theoretical analysis results and simulation experiments were tally close,which confirms the reliability of proposed models.The access strategies with handoff and channel reservation efficiently decrease the call dropping probability,as while as,increase the blocking probability.And the thought for CRN can reach the maximum in the latter with the optimum number of reserved channels.…”

    Channel interleaver design and performance analysis for ultrasonic through-metal communication by Linsen XU, Wei YANG, Hongxian TIAN

    Published 2022-10-01
    “…Aiming at the problem that the UTM channel can produce successive error bits, a multiple input channel interleaver for UTM communication was proposed.By taking advantages of the grouping idea in multiple input interleaver and the periodic oscillation characteristic of the power gain in the UTM channel, encoded bits were first divided into several groups so that error probabilities of bits in each group varied smoothly.And then, the shift operation and the rectangular interleaver were applied to encoded bits in each group.This not only ensured that interleaved bits in the same group were dispersed into different oscillation cycles, which avoided that the successive bits suffer the high error probability, but also maintained the original bit position sequences, which reduced the influence of UEP.Approximate BER performances for the random interleaver and the proposed interleaver were analyzed and verified by simulation.Simulation results indicate that the proposed interleaver increases the frequency diversity of the UTM communication system and has a lower BER than the random interleaver at high SNR.…”
