WitrynaThe Geni impurity tells us the probability that we select an object at random and a label at random and it is an incorrect match. The Geni impurity is the sum of the probabilities in the black shaded areas. These are where the label does not match the object, thus the impurity. This should look very familiar to the answer to question 2. WitrynaThe impurity function can be defined in different ways, but the bottom line is that it satisfies three properties.
