WitrynaThe gini impurity index is defined as follows: Gini ( x) := 1 − ∑ i = 1 ℓ P ( t = i) 2 The idea with Gini index is the same as in entropy in the sense that the more heterogenous and impure a feature is, the higher the Gini index. WitrynaThe original CART algorithm uses Gini impurity as the splitting criterion; The later ID3, C4.5, and C5.0 use entropy. We will look at three most common splitting criteria. 11.2.1 Gini impurity Gini impurity ( L. Breiman et al. 1984) is a measure of non-homogeneity. It is widely used in classification tree. WitrynaOne salutatory aspect of the risk reduction criteria not found in the impurity measures is inclusion of the loss function. Two different ways of extending the impurity criteria to also include losses are implemented in CART, the generalized Gini index and altered priors. The rpart software implements only the altered priors method. mcfly ricoré
