A projected gradient method for $α ℓ_{1} - β ℓ_{2}$ sparsity regularization

Liang Ding, Weimin Han

The non-convex $α ∥ \cdot ∥_{ℓ_{1}} - β ∥ \cdot ∥_{ℓ_{2}}$ $(α \geq β \geq 0)$ regularization has attracted attention in the field of sparse recovery. One way to obtain a minimizer of th…

$α ℓ_{1} - β ℓ_{2}$ sparsity regularization for nonlinear ill-posed problems

Liang Ding, Weimin Han

In this paper, we consider the $α ∥ \cdot ∥_{ℓ_{1}} - β ∥ \cdot ∥_{ℓ_{2}}$ sparsity regularization with parameter $α \geq β \geq 0$ for nonlinear ill-posed inverse problems. We investi…
