WitrynaA decision tree is the same as other trees structure in data structures like BST, binary tree and AVL tree. We can create a decision tree by hand or we can create it with a graphics program or some specialized software.

Build Better Decision Trees with Pruning by Edward Krueger

WitrynaPruning reduces the size of decision trees by removing parts of the tree that do not provide power to classify instances. Decision … WitrynaDecision tree pruning uses a decision tree and a separate data set as input and produces a pruned version that ideally reduces the risk of overfitting. You can split a unique data set into a growing data set and a pruning data set. These data sets are used respectively for growing and pruning a decision tree.
