Frank-wolfe算法步骤

WebThe Frank-Wolfe algorithm tries to choose more intelligently: at each iteration, is chosen to get as close to equilibrium as possible along the line connecting x to x. This is done by solving a \restricted" VI where the feasible set X is the line segment between x and x and the force points in the direction of t(x). WebWe introduce regularized Frank-Wolfe, a general and effective algorithm for in-ference and learning of dense conditional random fields (CRFs). The algorithm optimizes a nonconvex continuous relaxation of the CRF inference problem using vanilla Frank-Wolfe with approximate updates, which are equivalent to minimizing a regularized energy function.
