Scalable Plug-and-Play ADMM with Convergence Guarantees
Yu Sun, Zihui Wu, Xiaojian Xu +2
Plug-and-play priors (PnP) is a broadly applicable methodology for solving inverse problems by exploiting statistical priors specified as denoisers. Recent work has reported the st…
A Recursive Born Approach to Nonlinear Inverse Scattering
Ulugbek S. Kamilov, Dehong Liu, Hassan Mansour +1
The Iterative Born Approximation (IBA) is a well-known method for describing waves scattered by semi-transparent objects. In this paper, we present a novel nonlinear inverse scatte…
Learning optimal nonlinearities for iterative thresholding algorithms
Ulugbek S. Kamilov, Hassan Mansour
Iterative shrinkage/thresholding algorithm (ISTA) is a well-studied method for finding sparse solutions to ill-posed inverse problems. In this letter, we present a data-driven sche…
Bayesian Estimation for Continuous-Time Sparse Stochastic Processes
Arash Amini, Ulugbek S. Kamilov, Emrah Bostan +1
We consider continuous-time sparse stochastic processes from which we have only a finite number of noisy/noiseless samples. Our goal is to estimate the noiseless samples (denoising…
