Frank wolfe算法例题
WebDec 15, 2024 · The Frank-Wolfe algorithm uses step size and postulated convexity, which formulates a matrix of positive semidefinite quadratic form. Just like a convex function yields a global minimum at any local minimum on a convex set, by the definition of nonlinear programming, the concave quadratic function would yield a global maximum point at any … Web2.3 Vanilla Frank-Wolfe algorithm for MAP inference Since the continuous energy is differentiable, it is natural to apply first-order methods such as Frank-Wolfe [23] to solving (6) [41]. Starting from a feasible x0 2X, Frank-Wolfe approximately solves (6) by iterating the following steps, where ↵ k 2 [0,1] follows some stepsize scheme: pk 2 ...
