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. did hitler\\u0027s nephew serve in the us navy
