New fractional regularization framework enhances sparse signal recovery

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a novel unified fractional regularization framework designed for sparse signal recovery using the $\ell_1/\ell_p^q$ model. This framework establishes an equivalence between first-order stationary points of the $\ell_1/\ell_p^q$ formulation and the subtractive $\ell_1 - \alpha \ell_p$ model. The paper also presents a new recovery condition under the Restricted Isometry Property (RIP) and details a majorization-minimization (MM) algorithm for solving the problem, demonstrating superior performance in numerical experiments for MRI reconstruction.

    A Unified Fractional Regularization Framework for Sparse Recovery

    arXiv:2604.23184v1 Announce Type: cross Abstract: We propose a unified fractional regularization framework for sparse signal recovery based on the $\ell_1/\ell_p^q$ model. Our main theoretical contribution is the characterization of the equivalence between the first-order station…
