Linear Convergence of Plug-and-Play Algorithms with Kernel Denoisers
Arghya Sinha, Bhartendu Kumar, Chirayu D. Athalye +1
The use of denoisers for image reconstruction has shown significant potential, especially for the Plug-and-Play (PnP) framework. In PnP, a powerful denoiser is used as an implicit…
Structural Controllability of Bilinear Systems on
A. Sanand Amita Dilip, Chirayu D. Athalye
Structural controllability challenges arise from imprecise system modeling and system interconnections in large scale systems. In this paper, we study structural control of bilinea…
On the Contractivity of Plug-and-Play Operators
Chirayu D. Athalye, Kunal N. Chaudhury, Bhartendu Kumar
In plug-and-play (PnP) regularization, the proximal operator in algorithms such as ISTA and ADMM is replaced by a powerful denoiser. This formal substitution works surprisingly wel…
On Exact and Robust Recovery for Plug-and-Play Compressed Sensing
Ruturaj G. Gavaskar, Chirayu D. Athalye, Kunal N. Chaudhury
In Plug-and-Play (PnP) algorithms, an off-the-shelf denoiser is used for image regularization. PnP yields state-of-the-art results, but its theoretical aspects are not well underst…
On Plug-and-Play Regularization using Linear Denoisers
Ruturaj G. Gavaskar, Chirayu D. Athalye, Kunal N. Chaudhury
In plug-and-play (PnP) regularization, the knowledge of the forward model is combined with a powerful denoiser to obtain state-of-the-art image reconstructions. This is typically d…
Necessary condition on Lyapunov functions corresponding to the globally asymptotically stable equilibrium point
Chirayu D. Athalye, Harish K. Pillai, Debasattam Pal
It is well known that, the existence of a Lyapunov function is a sufficient condition for stability, asymptotic stability, or global asymptotic stability of an equilibrium point of…
