This paper studies first-order algorithms for solving fully composite optimization problems over convex and compact sets.

Faster One-Sample Stochastic Conditional Gradient Method for Composite Convex Minimization

1 code implementation26 Feb 2022 Gideon Dresdner, Maria-Luiza Vladarean, Gunnar Rätsch, Francesco Locatello, Volkan Cevher, Alp Yurtsever

We propose a stochastic conditional gradient method (CGM) for minimizing convex finite-sum objectives formed as a sum of smooth and non-smooth terms.

A first-order primal-dual method with adaptivity to local smoothness

no code implementations NeurIPS 2021 Maria-Luiza Vladarean, Yura Malitsky, Volkan Cevher

We consider the problem of finding a saddle point for the convex-concave objective $\min_x \max_y f(x) + \langle Ax, y\rangle - g^*(y)$, where $f$ is a convex function with locally Lipschitz gradient and $g$ is convex and possibly non-smooth.

Conditional gradient methods for stochastically constrained convex minimization

no code implementations ICML 2020 Maria-Luiza Vladarean, Ahmet Alacaoglu, Ya-Ping Hsieh, Volkan Cevher

We propose two novel conditional gradient-based methods for solving structured stochastic convex optimization problems with a large number of linear constraints.
