A Riemannian Alternating Direction Method of Multipliers

Mathematics of Operations Research
We consider a class of Riemannian optimization problems where the objective is the sum of a smooth function and a nonsmooth function considered in the ambient space. This class of problems finds important applications in machine learning and statistics, such as sparse principal component analysis, sparse spectral clustering, and orthogonal dictionary ...

Efficient JPEG decompression by the alternating direction method of multipliers

2016 23rd International Conference on Pattern Recognition (ICPR), 2016
Standard decompression of JPEG images produces artifacts along edges and a disturbing checkerboard pattern. To reduce these artifacts, decompression can be formulated as an image reconstruction problem within Bayesian maximum a posteriori probability framework. In this type of problem, the prior information about an image is typically given by the l 1

An alternating direction method of multipliers for sparse SAR imaging

2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014
In this paper, we present a solution to the constrained 1-norm minimization problem for sparse SAR imaging. The technique we present relies on recent advances in the solution of optimization problems, based on Augmented Lagrangian Methods (ALMs), in particular the Alternating Direction Method of Multipliers.
