NCestimation_V2
The NCT includes 4 External validity indices and 8 internal validity indices, and the sub-routine validity_Index.m is designed to use them.
This tool is suitable for the research work such as the performance comparison of different indices on estimation of the number of clusters, algorithm design by improving part codes of this toolbox.
i) External validity indices when true class labels are known:
Rand index
Adjusted Rand index
Mirkin index
Hubert index
ii) Internal validity indices when true class labels are unknown:
Silhouette
Davies-Bouldin
Calinski-Harabasz
Krzanowski-Lai
Hartigan
weighted inter- to intra-cluster ratio
Homogeneity
Separation
iii) Others
Error rate (compared with true labels)
System Evolution: it is used to estimate the number of clusters and give separable degrees between clusters.
