ID3 - Pruning

Saskia98

Hey guys, im new to rapidminer but I need to do something for Uni.

 

I read a CSV-File and then I discretized it. The task is to create a tree using the ID3-Algorithm. Then I have to prune it.

 

If i use the "ID3" operator i dont have the possibility to use pruning.

 

Do you have any ideas, how i can prune an ID3-Tree?

 

Thank you

I believe the ID3 approach has some inherent pruning during the testing phase as part of it's leaf spliting. Take a read through the operator reference here: https://docs.rapidminer.com/studio/operators/modeling/predictive/trees/id3.html
