Based on Minkowski's inequality for sums [2] with order 2: null null null null Using Eq. 1 and 3, Eq. 4 can be proved. Using Eq. 3, 10, and 2, we have the following distance (o Similar to proof in C, Theorem 4 can be proved. Using Eq. 11 and 3, Eq. 4 can be proved. So we prove the left inequality. The above proof shows that a better accuracy of an ensemble can be achieved by combining components with accuracy that is at least equal to the average accuracy of individual components (i.e.
