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 byDunn in 1973and improved byBezdek in 1981) is frequently used in pattern recognition. It is based on minimization of the following objective function: ,...
This example shows how FCM clustering works using quasi-random two-dimensional data. Load the data set and plot it. loadfcmdata.datplot(fcmdata(:,1),fcmdata(:,2),"o") Using thefcmfunction, find two clusters in this data set. The clustering algorithm stops when the improvement in the ...
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: 其中m>1 为模糊加权指数,U=[uij]c×n为 c 个聚类中心vi相对于 n 个样本数据点xj的隶属度矩阵,dij为欧氏距离。 引入拉格朗日乘子,把原带约束的优化问题转化为无约束的优化问题。

(c– 1). Then, each itemxiof the finite setXhas the flexibility of mapping to one or more clusters. Hence, a membership or affinity score is introduced here,uij, which is for itemxiwith respect toCj. This type of clustering is calledsoft clustering. Since it brings in an element of ...
fuzzy c mean In subject area: Computer Science Fuzzy c-means clustering is a fuzzy variant of the k-means algorithm that computes the centroid of a cluster as the mean of all examples, weighted by their degree of belonging to the cluster. AI generated definition based on: Machine Learning ...

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...
