Hi all:
I have a question about ID3 algorithm (sorry my english). Some documentation I read said that an atribut can't appear more than once in the tree. But in weka I saw atributes that appear several times in a tree. My question is:
this happen because of weka is not using ID3 algorithm (I'm using J48-similiar to C4.5, I think) or is because of only the most pure form of ID3 don't allow an atribute to appear more than once in a tree?

Thanks!
