Conjugate gradient acceleration of iteratively re-weighted least squares methods
Massimo Fornasier, Steffen Peter, Holger Rauhut +1
Iteratively Re-weighted Least Squares (IRLS) is a method for solving minimization problems involving non-quadratic cost functions, perhaps non-convex and non-smooth, which however…

Minimization of multi-penalty functionals by alternating iterative thresholding and optimal parameter choices
Valeriya Naumova, Steffen Peter
Inspired by several recent developments in regularization theory, optimization, and signal processing, we present and analyze a numerical approach to multi-penalty regularization i…

Damping Noise-Folding and Enhanced Support Recovery in Compressed Sensing
Marco Artina, Massimo Fornasier, Steffen Peter
The practice of compressed sensing suffers importantly in terms of the efficiency/accuracy trade-off when acquiring noisy signals prior to measurement. It is rather common to find…
