Decision Tree (Recursive Feature Elimination or RFE)

Hello,
For decision tree process, how can we use Recursive Feature Elimination (RFE) to select those features in a training dataset that are more or most relevant in predicting the target variable.
Thanks you.

    Hi,
    Likely you refer to what we call Backwards Elimination.

    Backwards Elimination is one feature selection method but it is not Recursive Feature Elimination (RFE) for feature selection.  Therefore, the result between these two feature selection methods may be different.
    It would be helpful, if Rapidminer can develop other feature selection methods for more flexibility of feature selection method.
    Anyway, thank you for your help and feedback.  
    Bgds.
