The Sum-Product Algorithm: the HMM Case The first step is to transform the directed graph of Fig. 16.15 to an undirected one; a factor graph or a junction tree graph. Note that this is trivial for this case, as the graph is already a tree. Let us work with the junction tree formulat...
edges of the graph. Denote the message from node X to node Y by µ X→Y (·) and note that, since either X or Y is a variable node, it is unambiguous to say that µ X→Y (·) is a function of its associated variable (either X or Y ). The sum-product algorithm approximat...
