无向图模型：

We have now presented three sets of independence assertions associated with a network structure H. For general distributions, I_p(H) is strictly weaker than I_l(H), which in turn is strictly weaker than I(H). However, all three definitions are equivalent for positive distributions.

 I_p(H): pairwise assumption

 I_l(H): local assumption

I(H): global assumption
