WebMethod of Multipliers (ADMM), the distributed linearized ADMM (L-ADMM) algorithm [14] achieves a linear rate of convergence to the global optimum if the global cost function satisfies the P-Ł condition. Similar results can be found in [15] for both first-order and zeroth-order primal-dual algorithms. In this paper, we approach a nonconvex ... WebA standard model for image reconstruction involves the minimization of a data-fidelity term along with a regularizer, where the optimization is performed using proximal algorithms such as ISTA and ADMM. In plug-and-play (PnP) regularization, the proximal operator (associated with the regularizer) in ISTA and ADMM is replaced by a powerful image …
