The recoverability limit for superresolution via sparsity

Laurent Demanet, Nam Nguyen

We consider the problem of robustly recovering a -sparse coefficient vector from the Fourier series that it generates, restricted to the interval . The difficulty of t…

Collaborative Multi-sensor Classification via Sparsity-based Representation

Minh Dao, Nam H. Nguyen, Nasser M. Nasrabadi +1

In this paper, we propose a general collaborative sparse representation framework for multi-sensor classification, which takes into account the correlations as well as complementar…

Linear Convergence of Stochastic Iterative Greedy Algorithms with Sparse Constraints

Nam Nguyen, Deanna Needell, Tina Woolf

Motivated by recent work on stochastic gradient descent methods, we develop two stochastic variants of greedy algorithms for possibly non-convex optimization problems with sparsity…

Fast and Efficient Compressive Sensing using Structurally Random Matrices

Thong T. Do, Lu Gan, Nam H. Nguyen +1

This paper introduces a new framework of fast and efficient sensing matrices for practical compressive sensing, called Structurally Random Matrix (SRM). In the proposed framework,…

Exact recoverability from dense corrupted observations via minimization

Nam H. Nguyen, Trac. D. Tran

This paper confirms a surprising phenomenon first observed by Wright \textit{et al.} \cite{WYGSM_Face_2009_J} \cite{WM_denseError_2010_J} under different setting: given highly…
