Hello  @mb223223

Generally, we don't recommend looking into train error as the models overfit most of the times, but if you have any specific requirement here is the sample process to get training and testing error either using a split validation or cross-validation. I also attached the sample process files that you can import into rapidminer from File --> Import Process so that you can run them as well.

Split Validation: Training & Testing Error



Cross-Validation Training and Testing Error: This is inside cross-validation operator.


Hope this helps. Please inform if you need more information.
