摘要: 同经典的FCM算法及其派生算法一样,KFCM算法对噪声及初始化中心敏感,容易陷入局部最优值。针对以上问题,本文提出一种改进的KFCM算法。通过引入多种群协同量子粒子群混合模拟退火算法(MCQPSOSA)来优化KFCM算法,提高KFCM算法的搜索效率和全局搜索能力,使得算法较快地收敛到最优解。将改进算法用于构建入侵检测系统并通过模拟仿真实验表明,改进算法具有更好的检测性能,解决了传统的聚类算法在入侵检测中稳定性差、检测准确率低的问题。

Abstract: Like the classic FCM clustering algorithm and its derived algorithm, KFCM clustering algorithm is sensitive to the initial center and noise data and easy to fall into local optimal value. To solve these problems, this paper proposes a modified fuzzy clustering algorithm based on multipopulations cooperative quantum particle swarm hybrid simulated annealing algorithm(MCQPSOSA). In the improved KFCM algorithm, MCQPSOSA algorithm is introduced to improve search efficiency and global search capabilities. The improved algorithm is used to build intrusion detection system. Our experimental results show the proposed algorithm has more efficient performance which solve poor stability and low detection accuracy of the traditional clustering algorithms in intrusion detection.
