    An Association Rule Mining Scheme Based on Bit Operation and Reverse Index by Yulei Huang, Xiaoxia Luo, Qing Lin

    Published 2015-11-01
    “…An improved Apriori algorithm for association rule mining called Apriori-BR was proposed,which was based on bit operation and reverse index.Specifically,the reverse index from frequent itemsets to transactions was constructed firstly by scanning twice of database,and the reverse index was grouped by the length of transactions.Then in the mining process,bit operation was adopted to accelerate subset detection together with the dynamical elimination of invalid low-dimensional transactions.The numerical results show that the Apriori-BR proposed can substantially improve mining efficiency when compared with the conventional Apriori algorithm and the improved ones in the literature.…”

    Social-based routing in pocket switched networks by AOJiu-xin C, HENGao-jun C, ANGJing Y, HUZi-qing Z, IUBo L

    Published 2015-05-01
    “…In pocket switched network,how to make effective balance between the message delivery ratio and transmis-sion delay is a problem to be solved.A community-based PSN routing algorithm,named BridgingCom,is proposed.It uses local community detection method with aging mechanism and introduces the bridging centrality as the basis of for-warding decisions.The algorithm combines the analysis of node centrality with the structure of social mobile network,makes full use of the community relationship and activeness of nodes in PSN.Simulation results show that BridgingCom routing algorithm has better performance in the message delivery ratio and message average delay compared to a number of previously proposed algorithms.…”

    Fast blind detection of short-wave frequency hopping signal based on MeanShift by Zhengyu ZHU, Yu LIN, Zixuan WANG, Kexian GONG, Pengfei CHEN, Zhongyong WANG, Jing LIANG

    Published 2022-06-01
    “…In the complex short-wave channel environment, combined with time-frequency analysis technology, a fast blind detection algorithm of the connected domain labeled frequency hopping signals based on MeanShift algorithm was proposed to reduce the influence of various interference signals and noises on frequency hopping signals and realize blind detection of frequency hopping signals under low signal-to-noise ratio.Firstly, the channel environment gray-scale time-frequency map was filtered by the secondary gray-scale morphology to obtain the binary time-frequency map.Secondly, the maximum duration of the signal was calculated by the connected domain labeling algorithm.Then, the MeanShift algorithm was used to cluster the maximum duration of the signal.Finally, the clustering result was made a second judgment by combining with the adaptive double threshold.The simulation results show that the proposed algorithm can quickly separate various interference signals and sharp noise under low signal-to-noise ratio, and realize fast blind detection of frequency hopping signals without any prior information.It has high detection probability, strong anti-interference ability in short-wave channel environment, low computational complexity and high engineering practical value.…”
