Modern problems across science and engineering increasingly require high-dimensional modeling: models with more parameters than observations. It is now well understood that statistically reliable inference is still possible under such high-dimensional settings, provided one restricts to constrained subclasses of models with particular low-dimens...

While the „“1 minimization technique plays an important role in designing computationally tractable recovery methods in compressed sensing, its complexity is still impractical for many applications. An attractive alternative to the „“1 minimization is a family of greedy algorithms. We will discuss several greedy algorithms from the point of view...

A staggering amount of attention was recently devoted to the studyof compressed sensing and related areas using sparse priors in overparameterized linear models under versions of linear programming (LP) analysis. More recently popularity of the sparsity approach for the classical model ofgroup testing also increased.The threshold phenomenon was ...
