Webinequality (2.7). Moreover, by the symmetry of the definition, the variable −Xis sub-Gaussian if and only if X is sub-Gaussian, so that we also have the lower deviation inequality P[X≤ µ−t] ≤ e− t2 2σ2, valid for all t≥ 0. Combining the pieces, we conclude that any sub-Gaussian variable satisfies the concentration inequality WebThe Robin to Chernoff-Hoeffding’s Batman is the union bound. It shows how to apply this single bound to many problems at once. It may appear crude, but can usually only be significantly improved if special structure is available in the class of problems.

Web2 Chernoff Bound For a binary random variable, recall the Kullback–Leibler divergence is KL(pjjq) = pln(p=q) + (1 p)ln((1 p)=(1 q)): Theorem 2.1. (Relative Entropy Chernoff … 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. $\endgroup$

In the matrix setting, the analogous theorem concerns a sum of positive-semidefinite random matrices subjected to a uniform eigenvalue bound. Matrix Chernoff I [ edit]
WebChernoff-Cramer bound´ Under a finite variance, squaring within Markov’s in-equality (THM 7.1) produces Chebyshev’s inequality (THM 7.2). This “boosting” can be pushed … Webwhere the inequality is true through the application of Markov’s Inequality, and the second equality follows from the independence of X i.
