In the process attached, how could I replace the "retrive" block with the block "Loop files"?
So if the data files you want to loop are in RapidMiner repositories, then use the Loop Repository operator. If they are in flat files, then use Loop Files and embed in the appropriate Read "X" operator (i.e Read Excel, Read CSV, etc).
Hi Thomas, this is my process with loop files. When I try to start the process with my dataset, in the block "Validation" i read "MISSING LABEL.." How should I do? In another message, i send you my dataset!
Thank you very much
This is my dataset.
