Basis Pursuit Receiver Function [PDF]

open access: yes, 2014
Receiver functions (RFs) are derived by deconvolution of the horizontal (radial or transverse) component of ground motion from the vertical component, which segregates the PS phases. Many methods have been proposed to employ deconvolution in frequency as

Approximate Message Passing in Coded Aperture Snapshot Spectral Imaging [PDF]

open access: yes, 2015
We consider a compressive hyperspectral imaging reconstruction problem, where three-dimensional spatio-spectral information about a scene is sensed by a coded aperture snapshot spectral imager (CASSI).

Iterative Soft/Hard Thresholding with Homotopy Continuation for Sparse Recovery [PDF]

open access: yes, 2017
In this note, we analyze an iterative soft / hard thresholding algorithm with homotopy continuation for recovering a sparse signal $x^\dag$ from noisy data of a noise level $\epsilon$.

On the performance of algorithms for the minimization of $\ell_1$-penalized functionals [PDF]

open access: yes, 2009
The problem of assessing the performance of algorithms used for the minimization of an $\ell_1$-penalized least-squares functional, for a range of penalty parameters, is investigated.
