Impurity function
WitrynaDecision 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. A tree can be seen as a piecewise constant approximation. Witryna4 cze 2024 · A pure function guarantees that it always returns the same output given the same input parameters. In other words, you can replace its invocation with its return …
