Towards Designing Optimal Sensing Matrices for Generalized Linear Inverse Problems
We consider an inverse problem $\mathbf{y}= f(\mathbf{Ax})$, where $\mathbf{x}\in\mathbb{R}^n$ is the signal of interest, $\mathbf{A}$ is the sensing matrix, $f$ is a nonlinear function and $\mathbf{y} \in \mathbb{R}^m$ is the measurement vector.
Analysis of Sensing Spectral for Signal Recovery under a Generalized Linear Model
We define a notion for the spikiness of the spectrum of $\mathbf{A}$ and show the importance of this measure in the performance of the EP.
Approximate message passing for amplitude based optimization
We consider an $\ell_2$-regularized non-convex optimization problem for recovering signals from their noisy phaseless observations.
