"[SOLVED] metrics to evaluate based clusters centroids"

MarcosRL

Hello friends of the community. A query.

I need to apply some metrics for evaluating the quality of the clusters obtained.
I see rapid miner has only the following metrics to evaluate based clusters centroids:
Index bauldin davies
SumOfSquares
I wanted to know if there are third-party plugin to add more metrics, metrics such as:
silhouette index
Dunn's index
Goodman-Kruskal Index
Isolation Index
Jaccard Index
Rand Index
How I can create an operator with any of these metrics?

Hello

You could try this

http://rapidminernotes.blogspot.co.uk/2011/06/counting-clusters-part-r.html

It uses R to calculate a silhouette validity measure

You could generalise this to use other validity measures provided by R

Hello, thanks
I found this page with a plugin to implement (Average) operator and Cophenetic Silhouette Coefficient Correlation (CPCC) operator.
