Hi,
unfortunately we did not manage to create them until now.
If you have a special question about one parameter, feel free to ask

Hi,
Thank you for your reply

I am interested in clustering validation and performance measures
for example
I like to run various experiments on text data using different clustering algorithm and compare the results based on for example
Recall, percesion and cluster purity , I already know the categories ahead (supervised clustering )

I have the CVS rapidminer

Thank you

Hi,
then you could use the Operator Cluster2Prediction. It will match a clustername of an existing cluster attribute with a classname in an existing label attribute, so that the global matching is optimal.
Then the usual performance operators might be used.
