We developed a generalized expectation-maximization (GEM) hard thresholding reconstruction algorithm for sparse signal reconstruction from quantized Gaussian-noise corrupted

We developed an automatic hard thresholding method for reconstructing sparse signals from compressive samples and applied it to tomographic reconstruction from sparse projec-

Automatic hard thresholding for sparse signal reconstruction from NDE measurements Aleksandar Dogandžić.. Iowa State University, ald@iastate.edu

Most sparse reconstruction methods require tuning [30], where the tuning parameters are typically the noise or signal sparsity levels: the IHT, NIHT, and ` 0 -AP algorithms

However, the IHT and NIHT methods converge slowly, demanding a fairly large number of iterations, require the knowledge of the signal sparsity level, which is a tuning parameter,

Abstract—In this note, we analyze an iterative soft / hard thresholding algorithm with homotopy continuation for recov- ering a sparse signal x † from noisy data of a noise

Following the outcomes of the optimization, some of the resulting portfolios realized greater (standardized) returns than the market return, and the findings proved that using

The ART-treated AIDS simian model described in the present study could be employed for preclinical evalua- tion of the effects of possible strategies for eliminating viral reservoirs

This paper have considered the problem of state estimation for systems whose nonlinear terms satisfy an incremental quadrtic inequlity that is parameterized by a set of

However, the IHT and NIHT methods converge slowly, demanding a fairly large number of iterations, require the knowledge of the signal sparsity level, which is a tuning parameter,
