Examples
Consider a function that factorizes as follows:
- ,
with a corresponding factor graph shown on the right. Observe that the factor graph has a cycle. If we merge into a single factor, the resulting factor graph will be a tree. This is an important distinction, as message passing algorithms are usually exact for trees, but only approximate for graphs with cycles.
