    Hi,
    this is exactly what was rapidminer made for. So it's quite easy:
    1. Load the data
    2. Load the model
    3. Apply the model using "ModelApplier"
    4. Calculate performance using "ClassificationPerformance".

    Of course, your new data has to contain the real label...

    Hi,
    is your point key stuck?

    Use the ModelLoader with the XMLZipped as output type. Then use the ModelLoader for loading again. This should work...
