Loopy BP multiplies the same potentials multiple times. It is often over-con dent. Loopy BP … WebProb Learning (UofT) CSC412-Week 5-1/2 13/20. Stationary distribution We can nd the stationary distribution of a Markov chain by solving the eigenvector equation ATv= v and set ˇ= vT: vis the eigenvector of AT with eigenvalue 1.

Ising model In compact form, for all pairs (s;t), we can write st(x s;x t) = e xsxtWst = pairwise potential This only encodes the pairwise behavior. We might want to add unary node potentials as well s(x s) = e bsxs The overall distribution becomes p(x) / Y s˘t st(x s;x s) Y s s(x s) = exp n J X

Sum-product vs. Max-product The algorithm we learned is called sum-product BP and approximately computes the marginals at each node. For MAP inference, we maximize over x j instead of summing over them. This is called max-product BP.
