How do decision trees learn
WebThe decision trees implemented in scikit-learn uses only numerical features and these features are interpreted always as continuous numeric variables. Thus, simply replacing the strings with a hash code should be avoided, because being considered as a continuous numerical feature any coding you will use will induce an order which simply does ... WebDec 25, 2024 · Decision Trees are a type of machine learning algorithm that can be used to make predictions based on data. They are called "decision trees" because they work by creating a tree-like model of decisions, with each internal node representing a decision and each leaf node representing the predicted outcome. Decision Trees are widely used in …
