Nov 24, 2022 · Formula of Gini Index. The formula of the Gini Index is as follows: Gini = 1 − n ∑ i=1(pi)2 G i n i = 1 − ∑ i = 1 n ( p i) 2. where, ‘pi’ is the probability of an object being classified to a particular class. While building the decision tree, we would prefer to choose the attribute/feature with the least Gini Index as the root node.

A decision tree is a flowchart-like tree structure where an internal node represents a feature (or attribute), the branch represents a decision rule, and each leaf node represents the outcome. The topmost node in a decision tree is known as the root node. It learns to partition on the basis of the attribute value. ID3 stands for Iterative Dichotomiser 3 and is named such because the algorithm iteratively (repeatedly) dichotomizes (divides) features into two or more groups at each step.
