Progress in the analysis of loopy belief propagation has made for the case of networks with a single loop [18, 19, 2, 1]. For the sum-product (or "belief update") version it can be shown that: • Unless all the conditional probabilities are deter ministic, belief propagation will converge. proof by southern glazer login
