Fuzzy C-means (FCM) clustering algorithm is an important and popular clustering algorithm which is utilized in various application domains such as pattern recognition, machine learning, and data mining. Although this algorithm has shown acceptable performance in diverse problems, the current literature ...
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 ...
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...

An improved Fuzzy C-Means (FCM) algorithm, which is called Reliability-based Spatial context Fuzzy C-Means (RSFCM), is proposed for image segmentation in this paper. Aiming to improve the robustness and accuracy of the clustering algorithm, RSFCM integrates neighborhood correlation model with the...
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 is a clustering method that allows each data point to belong to multiple clusters with varying degrees of membership. To configure clustering options, create anfcmOptionsobject. The FCM algorithm computes cluster centers and membership values to minimize the following objective function. ...
