A scaled, inexact and adaptive Fast Iterative Soft-Thresholding Algorithm for convex image restoration
Luca Calatroni, Simone Rebegoldi
In this note, we consider a special instance of the scaled, inexact and adaptive generalised Fast Iterative Soft-Thresholding Algorithm (SAGE-FISTA) recently proposed in (Rebegoldi…

Scaled, inexact and adaptive generalized FISTA for strongly convex optimization
Simone Rebegoldi, Luca Calatroni
We consider a variable metric and inexact version of the FISTA-type algorithm considered in (Chambolle, Pock, 2016, Calatroni, Chambolle, 2019) for the minimization of the sum of t…
