Assume that I have a belief network with a set of nodes.
In order to create a valid junction tree I have to moralize the graph. Assume now that I have nodes with more than 2 parents (e.g 3 parents) then I have to link each of the parents. After doing that, the graphical models contain some unnecessary cliques. Can I use only a part of the cliques for the Junction Tree Creation? Or I must use every clique in the junction tree (e.g., a case with 8 nodes and 8 cliques)?
