Validation Index of Fuzzy Clustering

Description

Validation Index of Fuzzy Clustering

Usage

1

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, MPC, and CE index. Both three indexes calculated from fuzzy membership and data point.

Xie Beni index calculated compactness and separation of clustering.

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

Value

XB.index Xie Beni index

MPC.index Modified Partition Coeeficient

CE.index Classification Entropy
