recommendations! Published in 2018 at "Soft Computing"

DOI: 10.1007/s00500-018-3460-y

Abstract: The goal in sparse approximation is to find a sparse representation of a system. This can be done by minimizing a data-fitting term and a sparsity term at the same time. This sparse term imposes… read more here.

DOI: 10.1109/tcsii.2020.3045427

Abstract: Manipulators may often endure large-scale potential energy variations during kinematic control, producing unsafe oscillations of posture-hold effects. In this brief, for the first time, a sparse-optimization-based control method is proposed to simultaneously guarantee task accuracy… read more here.

DOI: 10.1109/tsipn.2022.3181729

Abstract: We propose a promising framework for distributed sparse optimization based on weakly convex regularizers. More specifically, we pose two distributed optimization problems to recover sparse signals in networks. The first problem formulation relies on statistical… read more here.
