Message Passing for Max-weight Indep endent Set Sujay Sanghavi, Devavrat Shah, Alan Willsky Poster ID T45 We study max-product MWIS on general graphs. We · Show that if LP relaxation lo ose max-product cannot converge. · Develop a certificate of optimality that can be checked at fixed-points of max-product. · Show that a simple two-sided mo dification of max-product always succeeds whenever LP relaxation is tight, · Show that any MAP estimation problem can be reduced to a MWIS problem. 5 3 = Both nodes cannot be "on" at same time. 1 3 Original Graph Resulting Pairwise MRF
