Iteratively re-weighted least squares minimization for sparse recovery
Ingrid Daubechies, Ronald DeVore, Massimo Fornasier +1
We analyze an Iteratively Re-weighted Least Squares (IRLS) algorithm for promoting l1-minimization in sparse and compressible vector recovery. We prove its convergence and we estim…

Approximation and learning by greedy algorithms
Andrew R. Barron, Albert Cohen, Wolfgang Dahmen +1
We consider the problem of approximating a given element from a Hilbert space by means of greedy algorithms and the application of such procedures to the regressi…

Approximation using scattered shifts of a multivariate function
Ronald DeVore, Amos Ron
The approximation of a general -variate function by the shifts , $ξ\inΞ\subset \Rd$, of a fixed function occurs in many applications such as data fitting, ne…
