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…
Parallel proximal methods for total variation minimization
Ulugbek S. Kamilov
Total variation (TV) is a widely used regularizer for stabilizing the solution of ill-posed inverse problems. In this paper, we propose a novel proximal-gradient algorithm for mini…
Isotropic inverse-problem approach for two-dimensional phase unwrapping
Ulugbek S. Kamilov, Ioannis N. Papadopoulos, Morteza H. Shoreh +2
In this paper, we propose a new technique for two-dimensional phase unwrapping. The unwrapped phase is found as the solution of an inverse problem that consists in the minimization…
A Learning Approach to Optical Tomography
Morteza H. Shoreh, Ulugbek S. Kamilov, Ioannis N. Papadopoulos +4
We describe a method for imaging 3D objects in a tomographic configuration implemented by training an artificial neural network to reproduce the complex amplitude of the experiment…
Inference for Generalized Linear Models via Alternating Directions and Bethe Free Energy Minimization
Sundeep Rangan, Alyson K. Fletcher, Philip Schniter +1
Generalized Linear Models (GLMs), where a random vector is observed through a noisy, possibly nonlinear, function of a linear transform arise…
