Activity Identification and Local Linear Convergence of Douglas--Rachford/ADMM under Partial Smoothness
Jingwei Liang, Jalal Fadili, Gabriel Peyré +1
Convex optimization has become ubiquitous in most quantitative disciplines of science, including variational image processing. Proximal splitting algorithms are becoming popular to…
Lagrange Multipliers, (Exact) Regularization and Error Bounds for Monotone Variational Inequalities
C. Charitha, Joydeep Dutta, D. Russell Luke
We examine two central regularization strategies for monotone variational inequalities, the first a direct regularization of the operative monotone mapping, and the second via regu…
Proximal Heterogeneous Block Input-Output Method and application to Blind Ptychographic Diffraction Imaging
Robert Hesse, D. Russell Luke, Shoham Sabach +1
We propose a general alternating minimization algorithm for nonconvex optimization problems with separable structure and nonconvex coupling between blocks of variables. To fix our…
