Chernoff-hoeffding inequality
WebI think of a "reverse Chernoff" bound as giving a lower estimate of the probability mass of the small ball around 0. I think of a small ball inequality as qualitatively saying that the small ball probability is maximized by the ball at 0. In this sense reverse Chernoff bounds are usually easier to prove than small ball inequalities. $\endgroup$ Webwhere the inequality is true through the application of Markov’s Inequality, and the second equality follows from the independence of X i. Note that Ees(X i−EX i) is the moment-generating function of X i −EX i. Lemma 2.1 (Hoeffding). For a random variable X with EX = 0 and a ≤ X ≤ b then for s > 0
Chernoff-hoeffding inequality
Did you know?
Chernoff bounds may also be applied to general sums of independent, bounded random variables, regardless of their distribution; this is known as Hoeffding's inequality. The proof follows a similar approach to the other Chernoff bounds, but applying Hoeffding's lemma to bound the moment generating functions (see Hoeffding's inequality). Hoeffding's inequality.
