WebJan 7, 2015 · Abstract: In order to compute the marginal probability density function (PDF) with Gaussian belief propagation (BP), it is important to know whether it will converge in advance. By describing the message-passing process of Gaussian BP on the pairwise factor graph as a set of updating functions, the necessary and sufficient convergence … Gaussian belief propagation is a variant of the belief propagation algorithm when the underlying distributions are Gaussian. The first work analyzing this special model was the seminal work of Weiss and Freeman. The GaBP algorithm solves the following marginalization problem: where Z is a normalization constant, A is a symmetric positive definite matrix (inverse covarianc…
