Sparse signal reconstruction with a sign oracle
Résumé
Sparse signal reconstruction is performed by minimizing the sum of a least-squares fit regularized with a piecewise rational approximation of 0. We show the benefit of an oracle that yields the sign of the signal when using a recent methodology for global polynomial or semi-algebraic minimization. The computational time and memory cost are both decreased
