Koopman operator theory shows how nonlinear dynamical systems can be represented as an infinite-dimensional, linear operator acting on a Hilbert space of observables of the system.

Many graphical models, such as Markov Logic Networks (MLNs) with evidence, possess highly symmetric substructures but no exact symmetries.

Our algorithm combines and generalizes recent work on anytime search and probabilistic bounds of the partition function.

We propose a simple Monte Carlo based inference method that augments convex variational bounds by adding importance sampling (IS).

The KL divergence is optimized using the belief propagation algorithm, with complexity exponential in only the cluster size of the graph.

We study the problem of estimating continuous quantities, such as prices, probabilities, and point spreads, using a crowdsourcing approach.

Since the development of loopy belief propagation, there has been considerable work on advancing the state of the art for approximate inference over distributions defined on discrete random variables.

We show that the LDLC decoder is an instance of non-parametric belief propagation and further connect it to the Gaussian belief propagation algorithm.
