Documentation
Definition
Subsequent extended reduction of a decision tree down to the essentials. Everything that can be removed without having a significant negative effect on the accuracy of the result is removed.
Use
Extended pruning checks whether greater accuracy is achieved when the current node is replaced by its major branch. If so, it retains this major branch and removes the current node and all its lower-level nodes.
Large datasets may cause extended pruning to be very time-consuming.
