Regression tree pruning reduces the risk of overfitting by verifying the predictive utility of all nodes of a regression tree. PEP - Policy Enforcement Point.

In this paper, we developed highly accurate ensemble machine learning models integrating Reduced Error Pruning Tree (REPT) as a base classifier with the.

Nodes that do not improve the expected prediction quality on new data are replaces by leaves.

Resetting to computed prune level To reset the model to the computed prune level,.

Reduced Error Pruning is an algorithm that has been used as a representative technique in attempts to explain the problems of decision tree learning. Pruning removing the subtree at that node, make it a leaf and assign the most common class at that node A node is removed if the resulting tree performs no worse then the original on the validation set - removes coincidences and errors. .

Pruning is a data compression technique in machine learning and search algorithms that reduces the size of decision trees by removing sections of the tree that are non-critical and redundant to classify instances. maxdepthint, defaultNone.
