摘要
为提高粒子群优化聚类算法的性能,结合特征分析相关方法,提出一种新的串联聚类算法KPCA-PSO,阐述算法的基本原理和实施方案。在特征分析过程中,以一种简单有效的特征值选择方法避免手动选择特征值的繁琐过程。以人工数据和实际数据测试算法性能,实验结果表明该方法具有较好的聚类效果。
Combined with the related method of feature analysis,a new cascading clustering method named KPCA-PSO is proposed to enhance the effect of Particle Swarm Optimization(PSO) clustering algorithm.Basic principles and detailed realization of the method are illustrated.In the process of feature analysis,a simple and effective feature selection method is put forward to avoid the boring manual feature selection.The method is evaluated on artificial data and real data,and experimental results show that it gains good clustering effect.
