WebOct 23, 2024 · The CART decision tree algorithm uses the Gini index to select partition attributes, which is defined as: Gini (D) = ∑k=1 ∑k'≠1 pk·pk' = 1- ∑k=1 pk·pk. The Kini index can be interpreted as the probability of inconsistencies in the class labels of two samples randomly sampled from dataset D. The smaller the Gini (D), the higher the purity.
