Web4.1 Factor graphs. Factor graphs are capable of capturing structure that the traditional directed and undirected graphical models above are not capable of capturing. A factor graph consists of a vector of random variables x = (x. 1,..., x. N) and a graph G = (V, E, F), which in addition to normal nodes also has factor nodes F. Furthermore, the ...
