Abstract:Employing the scaled memoryless BFGS (Broyden-Fletcher-Goldfarb-Shanno) updating formula, a multiplier of the identity matrix is proposed as an estimation of the inverse Hessian of the objective function. Incorporated into the proximal operator, the suggested spectral gradient vector has been employed to solve the nonsmooth sparse recovery problem. Taking sparsity property into consideration, a nonmonotone backtracking line search technique is put forward which is adjusted for the nonsmooth sparse recovery cos… Show more
