More advanced algorithms related to k means areExpected Maximization (EM) algorithmespeciallyGaussian Mixture, Self-Organization Map (SOM) from Kohonen, Learning Vector Quantization (LVQ). To overcome weakness of k means, seve...
考虑到k-means算法的先天不足, 本文提出了一种基于粒子群和复合形法的改进的k均值聚类算法 (Complex-PSO and k-means Clustering Algorithm) , 简称COPSOK算法。改进后的kmeans算法可以选择适当的初始聚类中心点, 同时也能得到更好的聚类结果。 1 k-means聚类算法 k-means算法的基本思想是, 以k为参数, 把n个...

K mean clustering algorithmcluster analysisK means clustering algorithm is applied to the field of intrusion detection,it has the following problems.First,cluster analysis does not consider the correlation degree of the data flow,so clustering accuracy is not high;the second is prone to packet loss...
【摘要】 K-mean是一个无监督的聚类算法(unsupervised clustering algorithm), 它简单快速, O(n)的运算复杂度。但是,该算法的有效性通常受到初始聚类中心点的影响。虽然学术界已经有很多方法被提出, 用来提高初始聚类中心点选取。但是,受数据集的影响,其效果也不理想。所以, 一直以来k-means聚类初始中心点选取问题一...
