其次对改进Fuzzy C-means算法进行文献回顾,对其概况、基本思想、算法进行详细介绍,再是应用了改进Fuzzy C-means算法,本文的数据是由所设计地软件在微博平台上获取的数据,最后得到相关结论和启示。 改进Fuzzy C-means 聚类算法是由 Steinhaus1955 年 Lloyd195年Ball&Hall1965 年 McQueen1967 年分别在各自的不同的科学...
In this work, we performed the initialization step for Fuzzy C-means (FCM) clustering algorithm using Ant Colony Optimization (ACO). Also, Mahalanobis distance metric is used instead of Euclidean distance metric in clustering process to avoid any relative dependency upon the geometrical shapes of ...

浅谈模糊C均值聚类(Fuzzy C-means Clustering) 定义:模糊c-均值聚类算法 fuzzy c-means algorithm (FCMA)或称( FCM)。在众多模糊聚类算法中,模糊C-均值( FCM) 算法应用最广泛且较成功,它通过优化目标函数得到每个样本点对所有类中心的隶属度,从而决定样本点的类属以达到自动对样本数据进行分类的目的。 假设样本集...
The Algorithm Fuzzy c-means (FCM) is a method of clustering which allows one piece of data to belong to two or more clusters. This method (developed by Dunn in 1973 and improved by Bezdek in 1981) is frequently used in pattern recognition. It is based on minimization of the following ...
令X={x1,x2,⋯,xn} 为含有至少 c<n 个空间分布较远点的数据样本点集, FCM 的代价函数定义为: Jm(U,v)=∑i=1c∑j=1nuijm(vi−xi)2=∑i=1c∑j=1nuijmdij2(vi,xj)s.t.∑i=1cuij=1 其中m>1 为模糊加权指数, U=[uij]c×n ...
改进Fuzzy C-means算法** Fuzzy C-means算法概述 Fuzzy C-means算法是聚类算法中主要算法之一,它是一种基于划分的聚类算法,是最为经典的,同时也是使用最为广泛的一种基于划分的聚类算法,它属于基于距离的聚类算法。1967年,J.B.MacQueen提出的Fuzzy C-means算法是目前为止在工业和科学应用中一种极有影响的聚类技术...
Fuzzy C-means算法主要是比较RGB空间的每个像素值与Cluster中的每个中心点值,最终给 每个像素指派一个值(0~1之间)说明该像素更接近于哪里Cluster的中心点,模糊规则是该像 素对所有cluster的值之和为1。简单的举例:假设图像中有三个聚类cluster1,cluster2,cluster3, ...
