Hi
I am trying to set up the cross validation together with LDA. I used the cross validation operator with the output of the process documents operator as input. In the training half of the cross validation, I have the LDA operator. This model is then passed on to the test part. There I apply the model and I have this linked to a performance operator. When I run it, the apply model operator returns an error "The attribute documentid was already present in the example set." No idea how to resolve this?

To use the XML, you need to open a new process in rapidminer. After that, you need to go to View --> Show Panel --> XML present in the menu bar of rapdiminer. You need to copy the XML code provided in the above post and paste it in the XML window of rapidminer, then click the green tick mark on the XML window and you can see the process mention by rodrigo in your RM.
Thanks,
