Query: Approximate Inference via Weighted Rademacher Complexity   Rademacher complexity is often used to characterize the learnability of a
hypothesis class and is known to be related to the class size. We leverage this
observation and introduce a new technique for estimating the size of an
arbitrary weighted set, defined as the sum of weights of all elements in the
set. Our technique provides upper and lower bounds on a novel generalization of
Rademacher complexity to the weighted setting in terms of the weighted set
size. This generalizes Massart's Lemma, a known upper bound on the Rademacher
complexity in terms of the unweighted set size. We show that the weighted
Rademacher complexity can be estimated by solving a randomly perturbed
optimization problem, allowing us to derive high-probability bounds on the size
of any weighted set. We apply our method to the problems of calculating the
partition function of an Ising model and computing propositional model counts
(#SAT). Our experiments demonstrate that we can produce tighter bounds than
competing methods in both the weighted and unweighted settings.
