This paper transmits a FORTRAN-IV coding of the fuzzy c-means (FCM) clustering program. The FCM program is applicable to a wide variety of geostatistical data analysis problems. This program generates fuzzy par
The fuzzy c-means (FCM) algorithm is a popular method for data clustering and image segmentation. However, the main problem of this algorithm is that it is very sensitive to the initialization of primary clusters, so it may not perform well in segmenting complex images. Another problem with ...

To utilize the expert knowledge and numerical data in a fuzzy model synchronously, this paper proposed a hybrid fuzzy c-means (FCM) clustering algorithm and Fuzzy Network (FN) method-based model for prediction. The Mamdani rule-based structure of the proposed model is identified based on FCM ...
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...

1.Because the spatial information is not considered in the traditional fuzzy c-means(FCM) clustering algorithm,the serious inaccuracies with synthetic aperture radar(SAR) image segmentation can be caused by using the FCM algorithm.传统模糊c-均值聚类算法没有考虑图像像素空间信息特征,在应用于合成孔径雷达...
FCM 是一种有目标的模糊聚类算法,其目标函数为: Jm(U,v)=∑i=1c∑k=1nxikm‖xk−vi‖2 式中,v = ( v1,v2,…,vc) ,m > 1 为模糊参数,该参数决 定了聚类的模糊度,也就是数据点可以成为多个类的程度,大多数情况下m = 2。当式( 2) 取到最小值时结果最优。对于聚类中心,其取值为 因为...
