WebHoeffding'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 . WebJun 25, 2024 · The proof is on page 7 of this pdf: http://cs229.stanford.edu/extra-notes/hoeffding.pdf Namely, the proof claims that Z − Z ′ is symmetric around the origin, and therefore a random sign variable S ( Z − Z ′) will have exactly the same distribution as Z − Z ′.

WebNov 17, 2015 · Richard Combes We derive an extension of McDiarmid's inequality for functions with bounded differences on a high probability set (instead of almost surely). … WebProof. The proof uses elementary calculus and convexity. First we note that the function `(x) ˘ esx is convex on R. Any x 2[a,b] can be written as x ˘ x¡a b¡a b¯ b¡x b¡a a. Hence esx • x¡a b¡a esb ¯ b¡x b¡a esa. Since EX ˘0, we have E £ esX b b¡a esa ¡ a b¡a esb µ b b¡a a b¡a es(b¡a) esa. We have s(b ¡a) in the exponent in the parentheses.To get the same thing in the ...
