WebThe node impurity is a measure of the homogeneity of the labels at the node. The current implementation provides two impurity measures for classification (Gini impurity and entropy) and one impurity measure for regression (variance). WebFeb 4, 2024 · Purity is a measurement of percentage composition of a chemical which serves as an impurity in a particular sample. It can be considered a type of quantitative assay. As an example, laboratory-grade ethanol comes as 95% ethanol. That means; the 95% of the sample contains ethanol, and water takes the rest of the 5% of it.
