Example of a Classification Tree
-
after allowing a huge expansion of the tree, we could revise a splitting mode
in a node removing branches and leaves, and only maintaining the node.
This technique is known as ”postpruning”.
The works that have inspired a lot of successive papers in the task of the
decision trees are [3] and [23]. In our experiments, we use the well-known decision
tree induction algorithm, ID3 [23].
