WebMar 8, 2024 · The tools are also effective in fitting non-linear relationships since they can solve data-fitting challenges, such as regression and classifications. Summary. Decision trees are used for handling non-linear data sets effectively. The decision tree tool is used in real life in many areas, such as engineering, civil planning, law, and business. WebMore precisely, I don't understand how Gini Index is supposed to work in the case of a regression tree. The few descriptions I could find describe it as : gini_index = 1 - sum_for_each_class (probability_of_the_class²) Where probability_of_the_class is just the number of element from a class divided by the total number of elements.
