TLDR
A parallel algorithm for solving the l1- compressive sensing problem takes advantage of shared memory, vectorized, parallel and many-core microprocessors such as Graphics Processing Units (GPUs) and standard vectorized multi-core processors (e.g. quad-core CPUs).
Abstract
This paper describes a parallel algorithm for solving the l1- compressive sensing problem. Its design takes advantage of shared memory, vectorized, parallel and many-core microprocessors such as Graphics Processing Units (GPUs) and standard vectorized multi-core processors (e.g. quad-core CPUs). Experiments are conducted on these architectures, showing evidence of the efficiency of our approach.

Parallelization of Fast 1-Minimization for Face Recognition

TL;DR: In this article, the augmented Lagrangian method (ALM) solvers are used for face recognition in both GPU and CPU hardware, and the proposed implementations significantly out-perform naive library-based implementations.

High-performance and Hardware-aware Computing, Proceedings of the First International Workshop on New Frontiers in High-performance and Hardware-aware Computing (HipHaC'11)

TL;DR: This work analyzes Convey’s programming paradigm and the associated programming effort, and presents practical results on the HC-1, a dual-target compiler that interprets pragma-extended C/C++ or Fortran code and produces implementations running on both, host and accelerator.

Robust Face Recognition via Sparse Representation

TL;DR: This work considers the problem of automatically recognizing human faces from frontal views with varying expression and illumination, as well as occlusion and disguise, and proposes a general classification algorithm for (image-based) object recognition based on a sparse representation computed by C1-minimization.

Gradient Projection for Sparse Reconstruction: Application to Compressed Sensing and Other Inverse Problems

TL;DR: This paper proposes gradient projection algorithms for the bound-constrained quadratic programming (BCQP) formulation of these problems and test variants of this approach that select the line search parameters in different ways, including techniques based on the Barzilai-Borwein method.
