针对现有基于核方法的直觉模糊聚类算法对初始值敏感、收敛速度慢等缺陷,利用粒子群优化算法全局搜索能力强、收敛速度快的优势,对直觉模糊核聚类算法的初始聚类中心进行优化,并提出了一种基于粒子群优化的直觉模糊核聚类算法。该算法在提升聚类性能的同时,有效增强了算法的收敛速度。在实验阶段,采用4组标准数据集对该算法进行了分类实验及有效性测试,并将其与模糊c均值聚类算法及直觉模糊c均值聚类算法的分类效果及运行时间进行对比,实验结果充分表明了该算法的有效性及优越性。
The intuitionistic fuzzy kernel e-means clustering algorithm has several problems such as sensitivity to the ini- tial value, low convergence speed, etc. To overcome these shortages, the particle swarm optimization (PSO) algorithm with powerful ability of global search and quick convergence rate is applied to intuitionistic fuzzy clustering. Firstly, PSO is used to optimize the initial clustering centers. Then, the approach of intuitionistic fuzzy kernel clustering based on PSO, namely PS-IFKCM, is proposed. This algorithm can enhance both the clustering ability and the convergence speed. Fi- nally, experiments based on four measured datasets are carried out to illustrate the performance of the proposed method. Compared with results from FCM and IFKCM, PS-IFKCM is of great efficiency for classification.
