WebIn 1956, M. Frank and P. Wolfe [ 5] published an article proposing an algorithm for solving quadratic programming problems. In the same article, they extended their algorithm to the following problem: \min_ {x\in S} f (x), (1) where f ( x) is a convex and continuously differentiable function on R n. The set S is a nonempty and bounded ...

The Frank-Wolfe algorithm is an iterative first-order optimization algorithm for constrained convex optimization, first proposed by Marguerite Frank and Philip Wolfe from Princeton University in 1956. It is also known as the … WebSpecifically, we introduce stochastic Riemannian Frank-Wolfe methods for nonconvex and geodesically convex problems. We present algorithms for both purely stochastic optimization and finite-sum problems. For the latter, we develop variance-reduced methods, including a Riemannian adaptation of the recently proposed Spider technique. horttechnology abbreviation
