    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.
