Hi!
Yes. RapidMiner's Optimize Parameter operators are primarily meant for supervised learning methods (classification and regression).
Optimize Parameters expects a "performance vector". Usually this is coming from a cross-validation inside the optimization. But any operator that returns performances can be used.
Please check out the processes in the Samples repository, processes/07_Clustering.
Processes 08 and 09 show the usage of the
Cluster Distance Performance
operator.
This operator will deliver the necessary metric in your Optimize Parameters.
