Hoe ding inequality

Nettet1 Introduction The goal of this lecture is to introduce and prove the bounded di erence inequality (BDI). This is a concen- tration inequality that generalizes Hoe ding’s and that has found many uses in learning theory. Our rst use of it will be in the development of Rademacher complexity. NettetHoe ding Inequality Hoe ding inequality issimilar in spirit to Chebyshev inequalitybut it issharper. This is how it looks in a special case forBernoulli randomvariables: Hoe ding Inequality Let X 1;:::;X n ˘Bernoulli(p). Then for any ">0 P(jX n pj ") 2e 2n" 2 Remark: Hoe ding inequalitygives us a simple way to create acon dence interval
