WebMay 12, 2024 · Belief propagation (BP) is an algorithm (or a family of algorithms) that can be used to perform inference on graphical models (e.g. a Bayesian network). BP can …
WebAug 15, 2002 · The first generalization of BP is loopy belief propagation (LBP) [Frey and MacKay, 1997], which consists of BP in graphs with loops. LBP does not provide a guarantee on the convergence and on the ... WebTrained various Graph Neural Networks (GNNs) to perform loopy belief propagation on tree factor graphs and applied transfer learning to cycle graphs. Demonstrated GNNs' superior accuracy and generalisation on loopy graphs, achieving at least 9% MAE reduction compared to Belief Propagation.
WebMay 26, 2024 · Belief. The belief is the posterior probability after we observed certain events. It is basically the normalized product of likelihood and priors. Belief is the normalized product of the likelihood and prior. We take the probabilities we knew beforehand and introduce new knowledge received from the children.
