摘要 针对K-均值聚类算法对初始值敏感和易陷入局部最优的缺点,提出了一类新的聚类算法——基于差分演化的K-均值聚类算法,进而提出了基于自适应差分演化的K-均值聚类算法,并将新算法与传统的K-均值聚类算法和最近提出的几个同类聚类算法进行比较。实验结果表明,该类算法能比较有效地克服传统的K-均值聚类算法的缺点,算法具有较好的全局收敛能力,稳定性强、收敛速度快,且比较研究表明该类算法具有一定的竞争力。 After analyzing the disadvantage of the classical K-means clustering,we propose a novel K-means cluster analysis algorithm based on differential evolution algorithm and a K-means cluster analysis algorithm based on self-adaptive differential evolution algorithm to improve the classical K-means algorithm.Numerical experiment results show that the new algorithms can overcome the faults of the classical K-means algorithm,and converge quickly.Comparative research exposes the two proposed algorithms as competitive algorithms for clustering.
