Sparse Stochastic Processes and Discretization of Linear Inverse Problems
Emrah Bostan, Ulugbek S. Kamilov, Masih Nilchian +1
We present a novel statistically-based discretization paradigm and derive a class of maximum a posteriori (MAP) estimators for solving ill-conditioned linear inverse problems. We a…

Approximate Message Passing with Consistent Parameter Estimation and Applications to Sparse Learning
Ulugbek S. Kamilov, Sundeep Rangan, Alyson K. Fletcher +1
We consider the estimation of an i.i.d. (possibly non-Gaussian) vector $\xbf \in \R^n$ from measurements $\ybf \in \R^m$ obtained by a general cascade model consisting of a known l…
