"[SOLVED] metrics to evaluate based clusters centroids"
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?
regards

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

You could try this

It uses R to calculate a silhouette validity measure
You could generalise this to use other validity measures provided by R
