Preventing a decision tree from using a variable more than once

Hello,

I am using the node "Simple Regression Tree Learner" and I'm trying to prevent the tree from using each variable more than once. Is it possible? If so, how is it done?

Thanks,

Sagie

Hi Sagie, 

It is not possible to explicitly make the algorithm to use each variable once, but you might want to try to regulate it with the Limit number of levels (tree depth) option in the configuration dialog of the Simple Regression Tree Learner node. 

 

Best,
