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: ,...

In this paper, we reveal the inherent deficiency of FCM and propose a new fuzzy clustering method called Gaussian Collaborative Fuzzy C-means (GCFCM) to solve these problems. In GCFCM, Gaussian mixture model (GMM) and collaborative technology are adopted to enhance the ability of recognizing ...
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...
一本文是完全基于JAVA语言实现Fuzzy C-Means聚合算法,并可以运用到图像处理中实现简 单的对象提取。 一:数学原理 在解释数学原理之前,请先看看这个链接算是热身吧 http://home.deib.polimi.it/matteucc/Clustering/tutorial_html/cmeans.html。 看不懂没关系。我的解释足够详细,小学毕业都可以学会,本人就是小学毕...
令\boldsymbol{X}=\left\{x_{1}, x_{2}, \cdots, x_{n}\right\} 为含有至少 c<n 个空间分布较远点的数据样本点集, \mathrm{FCM} 的代价函数定义为: \begin{gathered} J_{m}(U, v)=\sum_{i=1}^{c} \sum_{j=1}^{…
Clustering is a classical data mining method applied on a set of items to group like items, thus separating unlike items. Most clustering algorithms give a definite mapping of an item to a cluster, referred to ashard clustering. But in real world, an item can belong to multiple clusters wit...

Fuzzy C-Means Clustering Fuzzy c-means(FCM) is a data clustering technique where each data point belongs to a cluster to a degree that is specified by a membership grade. The FCM algorithm starts with an initial guess for the cluster centers, which represent the mean location of each cluster...
