Such conclusion is experimentally verified when implementing the standard FCM and the maximum entropy clustering algorithm. Finally, the problems existing in these algorithms and the prospects of the fuzzy partitional algorithms are discussed.ZHANG Min...
模糊核函数特征空间聚类算法Outliers are data values that lie away from the general clusters of other data values. It may be that an outlier implies the most important feature of a dataset. In this paper, a new fuzzy kernel clustering algorithm is presented to locate the critical areas that ...
If you do not have a clear idea how many clusters there should be for a given set of data,subtractive clusteringis a fast, one-pass algorithm for estimating the number of clusters and the cluster centers for a set of data[2]. To obtain the cluster estimates, use thesubclustfunction. You...

The FCM clustering algorithm is a powerful unsupervised learning technique to form a few rules with simple and interpretable structure5. FCM induces rules by organizing and categorizing data into partitions. Partitions with homogeneous data form clusters, and each cluster is associated with a rule. Th...
Gath-Geva algorithm(also called Gaussian Mixture Decomposition): similar to FCM, but clusters can haveanyshape. Shape-based fuzzy clustering algorithms. Circular shaped: circular-shaped (CS) algorithms are what constrains data point to a circular shape. When this algorithm is incorporated into Fuzzy...
