In probability theory, Hoeffding's inequality provides an upper bound on the probability that the sum of bounded independent random variables deviates from its expected value by more than a certain amount. Hoeffding's inequality was proven by Wassily Hoeffding in 1963. Hoeffding's inequality is a special case of the Azuma–Hoeffding inequality and McDiarmid's inequality. It is similar to the Chernoff bound, but tends to be less sharp, in particular when the va… WebTheorem 1 Hoeﬀding’s Inequality Let Z 1,Z 2,...,Zn be independent bounded random variables such that Z i ∈ [a i,b i] with probability 1.
