to students and researchers in both communities. The interplay between optimization and …

Gradient projection for sparse reconstruction: Application to compressed sensing and other inverse problems

…, RD Nowak, SJ Wright - IEEE Journal of selected …, 2007 - ieeexplore.ieee.org
Many problems in signal processing and statistical inference involve finding sparse solutions
to under-determined, or ill-conditioned, linear systems of equations. A standard approach …

[BOOK][B] Primal-dual interior-point methods

SJ Wright - 1997 - SIAM
Linear programming has been the dominant paradigm in optimization since Dantzig's
development of the simplex method in the 1940s. In 1984, the publication of a paper by Karmarkar …

[PDF][PDF] Numerical optimization

SJ Wright - 2006 - shuyuej.com
This is a book for people interested in solving optimization problems. Because of the wide (and
growing) use of optimization in science, engineering, economics, and industry, it is …

[BOOK][B] Numerical optimization

J Nocedal, SJ Wright - 1999 - Springer
One of the most effective methods for nonlinearly constrained optimization generates steps
by solving quadratic subproblems. This sequential quadratic programming (SQP) approach …

Sparse reconstruction by separable approximation

SJ Wright, RD Nowak… - IEEE Transactions on …, 2009 - ieeexplore.ieee.org
Finding sparse approximate solutions to large underdetermined linear systems of equations
is a common problem in signal/image processing and statistics. Basis pursuit, the least …

Coordinate descent algorithms

SJ Wright - Mathematical programming, 2015 - Springer
… Liu and Wright [27] consider a version of Algorithm 7 that is the parallel analog of Algorithm
3, in that each update component \(i_k\) is chosen independently and randomly with equal …

Computational methods for sparse solution of linear inverse problems

JA Tropp, SJ Wright - Proceedings of the IEEE, 2010 - ieeexplore.ieee.org
The goal of the sparse approximation problem is to approximate a target signal using a linear
combination of a few elementary signals drawn from a fixed collection. This paper surveys …

Distributed MPC strategies with application to power system automatic generation control

…, IA Hiskens, JB Rawlings, SJ Wright - IEEE transactions on …, 2008 - ieeexplore.ieee.org
