"k-means validation"
Hello friends of the community. a query
I have made a cluster with k-means and would like to apply internal quality metrics, such as Sum of Squared Error (SSE) or Silhouette.Need to measure cohesion and separation of clusters.
Do these metrics in rapid miner?

I want to perform validation of some clusters with k-means performed with the metric "Silhouette" for this I downloaded the. Jar of this page:
Then copy the. Jar to the folder lib / plugins
then connect the output of the operator "k-means clustering," the operator "Silhouette" but it seems to me are missing something, because I get the following error
"Process failed: No data was delivered at port Performance.similarity (disconnected)."
accompanying the process xml regards
