Sketching for Simultaneously Sparse and Low-Rank Covariance Matrices
Sohail Bahmani, Justin Romberg
We introduce a technique for estimating a structured covariance matrix from observations of a random vector which have been sketched. Each observed random vector …
Efficient Compressive Phase Retrieval with Constrained Sensing Vectors
Sohail Bahmani, Justin Romberg
We propose a robust and efficient approach to the problem of compressive phase retrieval in which the goal is to reconstruct a sparse vector from the magnitude of a number of its l…
Near-Optimal Estimation of Simultaneously Sparse and Low-Rank Matrices from Nested Linear Measurements
Sohail Bahmani, Justin Romberg
In this paper we consider the problem of estimating simultaneously low-rank and row-wise sparse matrices from nested linear measurements where the linear operator consists of the p…
Lifting for Blind Deconvolution in Random Mask Imaging: Identifiability and Convex Relaxation
Sohail Bahmani, Justin Romberg
In this paper we analyze the blind deconvolution of an image and an unknown blur in a coded imaging system. The measurements consist of subsampled convolution of an unknown blurrin…
