Accelerated Plug-and-Play Davis-Yin Splitting for Nonconvex Image Reconstruction
Kuntal Roy, Pankaj Gautam
In this work, we study a class of structured non-convex and non-smooth optimization problems arising in imaging applications, where the objective is the sum of three functions. We…

Forward-backward-forward dynamics for bilevel equilibrium problem
Kanchan Mittal, Pankaj Gautam, V. Vetrivel
We introduce a forward-backward-forward (FBF) algorithm for solving bilevel equilibrium problem associated with bifunctions on a real Hilbert space. This modifies the forward-backw…

Degenerate preconditioned backward-backward splitting for inclusion problem
Pankaj Gautam, Vellaichamy Vetrivel
In this work, we introduce the notion of warped Yosida regularization and study the asymptotic behavior of the orbit of dynamical systems generated by warped Yosida regularization,…
