    Hi @s_na99,

    Here a process which performs what you want to do : 

    I put an Apply Model and a Performance operators in the training part of the Cross validation operator (to have the training error) : 



    BTW do you know that oyu can use the new Automatic Feature Engineering operator which performs automatically
    for you the Feaure selection and feature generation for you ?
    You can test it via submitting your data to AutoModel..or directly in RapidMiner  GUI...

    The process :
