Convergence Rate Analysis of a Stochastic Trust Region Method via Submartingales
Jose Blanchet, Coralia Cartis, Matt Menickelly +1
We propose a novel framework for analyzing convergence rates of stochastic optimization algorithms with adaptive step sizes. This framework is based on analyzing properties of an u…

Quantitative recovery conditions for tree-based compressed sensing
Coralia Cartis, Andrew Thompson
As shown in [Blumensath and Davies 2009, Baraniuk et al. 2010], signals whose wavelet coefficients exhibit a rooted tree structure can be recovered using specially-adapted compress…

Global rates of convergence for nonconvex optimization on manifolds
Nicolas Boumal, P. -A. Absil, Coralia Cartis
We consider the minimization of a cost function on a manifold using Riemannian gradient descent and Riemannian trust regions (RTR). We focus on satisfying necessary optimal…
