WitrynaPruning decision trees. Decision trees that are trained on any training data run the risk of overfitting the training data.. What we mean by this is that eventually each leaf will reperesent a very specific set of attribute combinations that are seen in the training data, and the tree will consequently not be able to classify attribute value combinations that … WitrynaPruning is a process of deleting the unnecessary nodes from a tree in order to get the optimal decision tree.
