WebThe naive and structured variational method have been formulated as message-passing algorithms by Bishop et al. [13], Xing et al. [42] and Geiger [41] in the notation of directed and undirected graphical models; variational message-passing algorithms have also been derived by means of factor graphs for certain speciﬁc cases [12, pp. 256–258] [15]. Webmessage-passing algorithms for both the non-convex and convex QP formulations. We use the concave-convex procedure (CCCP) to develop the message pass-ing algorithms [Yuille and Rangarajan, 2003]. Moti-vated by geometric programming [Boyd et al., 2007], we present another QP-based formulation of MAP and solve it using the CCCP technique. … how to draw mirrored clip studio paint
