How to Post Pruning in RapidMiner

RonaldSebastian58

Hi everyone, I’m having trouble with an overfitting decision tree and my teacher suggested using post-pruning to improve accuracy. However, I’m not sure how to apply post-pruning in RapidMiner. Can anyone offer some guidance?

Hi Ronald,

for the regular Decision Tree operator the "apply pruning" parameter together with the "confidence" parameter is used for post pruning.
