Proof of mcdiarmid inequality
WebJun 3, 2024 · In this paper, we obtain a Bernstein-type concentration inequality and McDiarmid’s inequality under upper probabilities for exponential independent random variables. Compared with the classical result, our inequalities are investigated under a family of probability measures, rather than one probability measure. WebApplying McDiarmid’s inequality to f then yields the result. Lemma 2.3. Define the function: f (x) = inf y2Y ff(y) + d c(x;y)g: Under assumption 1.2 we have (i) f (x) = )for all 2Y, and (ii) j …
