Proof of mcdiarmid inequality
Webconvergence. This lecture introduces Hoeffding’s Inequality for sums of independent bounded variables and shows that exponential convergence can be achieved. Then, a … WebThe step (10) is due to Jensen’s inequality, whereas (11) exploits the invariance of K. Since the inequality holds for all possible measure couples κ, we conclude K h (p µ)− h ϕ #ν ν 1 ≤ M∗ h W1 c µ,ϕ #), given that c≡L1. A similar inference can be drawn for a general class of metrics cby altering the

WebJan 15, 2024 · The McDiarmid’s inequality bounds the probability that the actual mean and expected mean of a function differ by more than a fixed quantity, given that the function does not deviate by a large amount on perturbing a single element. The actual proof then becomes simply manipulating the expectation and supremum using Jensen’s inequality ... WebNov 29, 2024 · Proof: In this proof, we will apply the McDiarmid's inequalities [49] to prove the two inequalities one by one.

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. WebThe proof of this theorem is in Section 3. The requirement of martingale in Theorem 3 seems to be even harder to satisfy than the requirement of independence. However, in many cases, we can construct a doob martingale ...
