Hello together, 

I am currently executing a Backward Elimination with contains a simple Naive Bayes by using Split Validation. But the subprocess is iterativeley working by switching between the milestones Naive Bayes --> Apply Model --> Performance and subsequently again starts with Naive Bayes (see attached). 

Is this procesdure normal? 

Thank you in advance for your answers! 

Best regards,

    yes, this is a normal procedure. 

    You can also use the Split Validation operator with the same operators inside: on the left side your learner (Naive Bayes), and on the right side Apply Model and Performance. This would be equivalent to your solution.

    Hi @BalazsBarany

    thank you for your answer. I tried this but the outgoing link of Split Validation has no "per" which is necessary for the subprocess of BackwardElimination. 

    Do you have a solution for this? 

    Best regards,
