PnP-IPA: A Provably Convergent Plug-and-Play Inexact Proximal Algorithm for Nonconvex Imaging Problems
This paper proposes a new splitting strategy that evaluates the proximal operator of the scaled implicit regularizer inexactly, and establishes global convergence to a stationary point of the nonconvex objective without imposing any assumption on the regularization parameter.
