Hoeffding inequality
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 variance of the random variables is small. [2] It is similar to, but incomparable with, one of Bernstein's inequalities . Se mer 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 … Se mer The proof of Hoeffding's inequality follows similarly to concentration inequalities like Chernoff bounds. The main difference is the use of Hoeffding's Lemma: Suppose X is a real random variable such that $${\displaystyle X\in \left[a,b\right]}$$ almost surely. Then Se mer • Concentration inequality – a summary of tail-bounds on random variables. • Hoeffding's lemma Se mer Let X1, ..., Xn be independent random variables such that $${\displaystyle a_{i}\leq X_{i}\leq b_{i}}$$ almost surely. Consider the sum of these … Se mer The proof of Hoeffding's inequality can be generalized to any sub-Gaussian distribution. In fact, the main lemma used in the proof, Se mer Confidence intervals Hoeffding's inequality can be used to derive confidence intervals. We consider a coin that shows … Se mer Nettetwhere for the second line we used the reproducing property of the RKHS, for the first inequality we used positive definiteness of k(X n;X n) + 2I n 2 that is a result of positive definiteness of k(X n;X n), and for the last inequality we used positive definiteness of k(X n;X n).
