And when we combine the node importances of all the non-terminal nodes in a tree, there won't be a bias towards say the root node. Ok. As for my second question though, that would reduce to asking whether we are guaranteed the existence of a (nontrivial) splitting that reduces impurity. Is that the case? | |
