Webcentralized Frank-Wolfe algorithm to solve the above prob-lem (1). It is nontrivial to design such an algorithm. We first provide a counterexample to show that the vanilla quan-tized decentralized Frank-Wolfe algorithm usually diverges (please see the following Counterexample section). Thus, there exists an important research problems to be ... WebTrace norm: Frank-Wolfe update computes top left and right singular vectors of gradient; proximal operator soft-thresholds the gradient step, requiring a singular value decomposition Many other regularizers yield e cient Frank-Wolfe updates, e.g., special polyhedra or cone constraints, sum-of-norms (group-based) regularization, atomic norms.

Websolution to ( 1 )(Frank & Wolfe , 1956 ; Dunn & Harsh-barger , 1978 ). In recent years, Frank-Wolfe-type methods have re-gained interest in several areas, fu-eled by the good scalability, and the crucial property that Algorithm 1 maintains its iterates as a convex combination of only few ÒatomsÓ s , enabling e.g. Webthe Frank-Wolfe algorithm can be used to solve more general problems than the ones described above. For example, it does not require any assumption on separability or sparsity of the objective. 1.2 Distributing Frank-Wolfe FW [15] is a convex optimization algorithm that solves the convex optimization problems of the form: Minimize F( ) subj. to ...
