Correlated Equilibria for Approximate Variational Inference in MRFs
Luis E. Ortiz, Boshen Wang, Ze Gong
Almost all of the work in graphical models for game theory has mirrored previous work in probabilistic graphical models. Our work considers the opposite direction: Taking advantage…
On Sparse Discretization for Graphical Games
Luis E. Ortiz
This short paper concerns discretization schemes for representing and computing approximate Nash equilibria, with emphasis on graphical games, but briefly touching on normal-form a…
Adaptive Importance Sampling for Estimation in Structured Domains
Luis E. Ortiz, Leslie Pack Kaelbling
Sampling is an important tool for estimating large, complex sums and integrals over high dimensional spaces. For instance, important sampling has been used as an alternative to exa…
Value-Directed Sampling Methods for POMDPs
Pascal Poupart, Luis E. Ortiz, Craig Boutilier
We consider the problem of approximate belief-state monitoring using particle filtering for the purposes of implementing a policy for a partially-observable Markov decision process…
