Junction Trees And Belief Propagation. Junction Trees: Motivation What if we want to compute all marginals, not just one? Doing variable elimination for.
A study of k-ordered hamiltonian graphs. Story begins L. Ng, M. Schultz, k-Ordered Hamiltonian graphs, J. Graph Theory 24 (1997) 45–57.
Junction Trees: Motivation Standard algorithms (e.g., variable elimination) are inefficient if the undirected graph underlying the Bayes Net contains cycles.
Internally Disjoint Paths Internally Disjoint Paths : Two paths u to v are internally disjoint if they have no common internal vertex.
