Perfect mapsMinimal I-maps are easy to find, but can containmany unnecessary dependencies.A BN structure G is called P-map (perfect map) fordistribution P if I(G) = I(P)Does every distribution P have a P-map?14
I-EquivalenceTwo graphs G, G’ are called I-equivalent if I(G) = I(G’)I-equivalence partitions graphs into equivalenceclasses15
