Description
Validation Index of Fuzzy Clustering
Usage
1
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, 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
