A projection‐based algorithm for ℓ2‐ℓp Tikhonov regularization

This paper deals with the minimization problem associated with Tikhonov regularization where the penalty term is a ℓp‐norm with p ∈ (1,2). An algorithm based on fixed‐point iterations is proposed, and theoretical convergence results are given. Further, combining projection over the Krylov subspace g...
