How does decision tree regression work
WebAug 2, 2024 · Decision trees are highly interpretable machine learning models that allow us to stratify or segment data. They allow us to continuously split data based on specific parameters until a final decision is made. How does the decision tree algorithm work? Take a look at the following table: WebDecision Tree Regression ¶ A 1D regression with decision tree. The decision trees is used to fit a sine curve with addition noisy observation. As a result, it learns local linear regressions approximating the sine curve.
