Convergence of the Frank-Wolfe Algorithm for Monotone Variational Inequalities

We consider the Frank-Wolfe algorithm for solving variational inequalities over compact, convex sets under a monotone \(C^1\) operator and vanishing, nonsummable step sizes. We introduce a continuous-time interpolation of the discrete iteration and use tools from dynamical systems theory to analyze its asymptotic behavior. This allows us to derive convergence results for the original discrete … Read more

Data-Dependent Complexity of First-Order Methods for Support Vector Machines

Large-scale problems in data science are often modeled with optimization and solved with first-order methods that may converge at a sublinear rate. It is of interest to terminate the optimization algorithm as soon as the underlying data science task is accomplished. We analyze the complexity of first-order methods for support vector machines (SVMs) in terms … Read more

A Primal-Dual Frank-Wolfe Algorithm for Linear Programming

We present two first-order primal-dual algorithms for solving saddle point formulations of linear programs, namely FWLP (Frank-Wolfe Linear Programming) and FWLP-P. The former iteratively applies the Frank-Wolfe algorithm to both the primal and dual of the saddle point formulation of a standard-form LP. The latter is a modification of FWLP in which regularizing perturbations are … Read more
