Inference in Credal Networks Through Integer Programming
Cassio Polpo de Campos, Fábio Gagliardi Cozman · Research Portal (Queen's University Belfast) · 2007
A credal network associates a directed acyclic graph with a collection of sets of probability measures; it offers a compact representation for sets of multivariate distributions. In this paper we present a new algorithm for inference in credal networks based on an integer programming reformulation. We are concerned with computation of lower/upper probabilities for a variable in a given credal network. Experiments reported in this paper indicate that this new algorithm has better performance than existing ones for some important classes of networks.
