Nov 30, 2018 · Decision Trees in Machine Learning. Decision Tree models are created using 2 steps: Induction and Pruning. Induction is where we actually build the tree i.e set all of the hierarchical decision boundaries based on our data. Because of the nature of training decision trees they can be prone to major overfitting. Decision Trees are a sort of supervised machine learning where the training data is continually segmented based on a particular parameter, describing the input and the associated output. Decision nodes and leaves are the two components that can be used to explain the tree. The choices or results are represented by the leaves.Decision Trees are a tree-like model that can be used to predict the class/value of a target variable.
