Nested subprocesses

patrick_de_win

Hello. I'd like to to operate the split validation process on a tree to rule process. Therefore I embedded the tree to rules (training) + apply model + performance (test) in the validation process. Then I embedded the decision tree process in the tree to rules process. Is this the right way to proceed? Thx for advice!

Yes, this works, although generally cross-validation is preferred to split validation--especially for learners like Decision Trees which are quite prone to overfitting.  So you might want to try that approach instead.
