We follow Pollard, Chapter 5. 1 Donsker Theorem Theorem 1 (Donsker Theorem: Uniform case). Let f˘ig be a sequence of iid Uniform[0,1] random variables. Let Un(t) = n 1=2 Xn i=1 [f˘i tg t] for 0 t 1 WebFirst, observe that KL divergence can be represented by its Donsker-Varadhan (DV) dual representation: Theorem 1 (Donsker-Varadhan representation). The KL divergence admits the following dual representa-tion: D KL(pjjq) = sup T:!R E p (x)[T] log(E q [e T]); (7) where the supremum is taken over all functions Tsuch that the two expectations are nite.

Web(DONSKER-VARADHAN Representation of KL-divergence). And Yu et al. [42] employ noise injection to manipulate the graph, and customizes the Gaussian prior for each input graph and the injected noise, so as to implement the IB of two graphs with a tractable variational upper bound. Our WebThe method uses the Donsker-Varadhan representation to arrive at the estimate of the KL divergence and is better than the existing estimators in terms of scalability and flexibility.
WebThe Donsker-Varadhan representation can be stated as D KL(PjjQ) = sup g:!R E P[g(X;Y)] log(E Q[eg(X;Y)]) (4) where the supremum is taken over all measurable functions gsuch that the expectation is finite. Now, depending on the function class, the right hand side of (4) yields a lower bound
