Bounds and estimates for BP convergence on binary undirected graphical models
Published on Feb 25, 20074422 Views
Belief Propagation (BP) has become a popular method for inference on graphical models. Accurate approximations for intractable quantities (e.g. single-node marginals) can be obtained within rather mod
