Hello. I use the latest version of Rapidminer, in the documentation there is an operator that I do not have and I can not find it. Does anyone know where to find the X-Prediction operator?

    Thanks for that helpful reply, Thomas.


    Is there any way to label the examples with the predictions - after the cross validation operator?


    If I use the "exa" output, I only see the examples, but without the predicted labels.


    If I save the model after the cross validation operator and then apply it to the same data set and use the "Performance" operator, I get labeled examples - but the accuracy is way higher than the results from the cross validation.


    My objective is to get the predicted labels of the examples, which match the performance vector, which I get from the 5-fold cross validation. Is that possible?


    Thanks in advance!

    Dear Jochen,


    the predicted examples are delivered at the "tes" port. they are only calculated if this port is connected.
