Witryna2 wrz 2013 · The Gini index (impurity index) for a node c can be defined as: i c = ∑ i f i ⋅ ( 1 − f i) = 1 − ∑ i f i 2. where f i is the fraction of records which belong to class i. If we have a two class problem we can plot the Gini index varying the relative number of records of the first class f. That is f 1 = f and f 2 = f − f 1.
