validation.index: Validation Index of Fuzzy Clustering

In AchmadFauzi/RcmdrPlugin.Fuzzcluster: R Commander Plug-in for Fuzzy Clustering Methods (Fuzzy C-Means and Gustafson Kessel)

Description

Validation Index of Fuzzy Clustering

Usage

validation.index(cluster)

Arguments

cluster

Cluster Result from Fuzzy Clustering

Details

This function provide validation index that calculated from fuzzy clustering result. There are 3 index that calculated, Xie Beni, Kwon, and Tang index. Both three indexes calculated from fuzzy membership and data point.

Xie Beni index calculated compactness and separation of clustering.

Kwon index extended Xie Beni index to eliminate its tendency to monotonically decrease when number of cluster approach the number of data point.

Tang index entended Kwon index to eliminate its tendency when fuzzifier aproaching to infinity

The best cluster result can be decided with minimum value of index.

Value

XB.index Xie Beni index

K.index Kwon index

T.index Tang index

MPC.index Modified Partition Coeeficient

CE.index Classification Entropy
