Decision Trees - scikit-learn documentation. Decision Trees ¶. Decision Trees (DTs) are a non-parametric supervised learning method used for classification and regression.
The goal is to create a model that predicts the value of a target variable by learning simple decision rules inferred from the data features. Clifton, VA Tree Pruning- Tree Pruning Service.

Pruning reduces the size of decision trees by removing parts of the tree that do not provide power to classify instances. Decision trees are the most susceptible out of all the machine learning algorithms to overfitting and effective pruning can reduce this likelihood. This post will go over two techniques to help with overfitting - pre-pruning.
