If ∑X∏a∈Afa(xa)=1 we will say that the factor graph is normalised and the proportionality in (1) can be replaced with equality. The sum-product algorithm, the main algorithm for calculating likelihoods and marginals, operate on graphs free of undirected cycles and with finite state ...

Belief propagation and many algorithms used in digital communications and signal processing are all representations of a more general message-passing algorithm, the sum-product algorithm, operating on factor graphs. This algorithm computes marginals of a global probabilistic function in terms of local fun...
