Optimization on Spheres: Models and Proximal Algorithms with Computational Performance Comparisons
D. Russell Luke, Shoham Sabach, Marc Teboulle
We present a unified treatment of the abstract problem of finding the best approximation between a cone and spheres in the image of affine transformations. Prominent instances of t…
Improved Complexities of Conditional Gradient-Type Methods with Applications to Robust Matrix Recovery Problems
Dan Garber, Shoham Sabach, Atara Kaplan
Motivated by robust matrix recovery problems such as Robust Principal Component Analysis, we consider a general optimization problem of minimizing a smooth and strongly convex loss…
Nonconvex Lagrangian-Based Optimization: Monitoring Schemes and Global Convergence
Jérôme Bolte, Shoham Sabach, Marc Teboulle
We introduce a novel approach addressing global analysis of a difficult class of nonconvex-nonsmooth optimization problems within the important framework of Lagrangian-based method…
