    Fixed Points of Loopy Belief Propagation as Zero Gradients of a Function of Reparameterizations

  • Original language description

    The existing view on loopy belief propagation sees it as an algorithm to find a common zero of a system of non-linear functions, not explicitly related to each other. We show that these functions are in fact related - they are the partial derivatives ofa single function of reparameterizations. Thus, belief propagation searches for a zero gradient of this function. We show that BP fixed points are in one-to-one correspondence to zero gradients of this function and that every zero gradient point of thisfunction is a saddle point.
