Characterization of Logarithmic Fekete Critical Configurations of at Most Six Points in All Dimensions

Diego Armentano, Leandro Bentancur, Federico Carrasco +3

We consider the logarithmic Fekete problem, which consists of placing a fixed number of points on the unit sphere in $R^{d}$ , in such a way that the product of all pairs of…

Re-Weighted $ℓ_{1}$ Algorithms within the Lagrange Duality Framework: Bringing Interpretability to Weights

Matías Valdés, Marcelo Fiori

We consider an important problem in signal processing, which consists in finding the sparsest solution of a linear system $Φ x = b$ . This problem has applications in several areas, bu…
