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.

Web18 jun. 2013 · 1 Answer. Here's a suggestion: create a closure which accepts a map containing the initial variables and their respective values as its key-value pairs for the first computation. The same closure returns an inner function that accepts another map with the remaining variables and values for the final computation.

Web2.1 Loopy Belief Propagation Loopy Belief Propagation (LBP) [20, 26] is an inference algorithm which approximately calculates the marginal distribution of unob-served variables in a probabilistic graphical model. We focus on LBP in a pairwise Markov Random Field (MRF) among other prob-abilistic graphical models to simplify the explanation. A ... WebMoreover, Belief Propagation is used in image processing for stereo matching . Again, a hardware implementation on a FPGA has shown to speed up Belief Propagation and the matching process as in . Also, in the field of compressed sensing Message Passing Algorithm similar to Belief Propagation and designed for FPGAs can be found [8,9].
