A Fast Phase-Based Enumeration Algorithm for SVP Challenge through y-Sparse Representations of Short Lattice Vectors
public-key cryptography Lattice-based Xryptography
2016/1/5
In this paper, we propose a new phase-based enumeration algorithm based on two
interesting and useful observations for y-sparse representations of short lattice vectors in lattices
from SVP challeng...
Recovering Non-negative and Combined Sparse Representations
underdetermined linear system sparse representations non-negative constraints orthogonal matching pursuit unique sparse solution
2013/5/2
The non-negative solution to an underdetermined linear system can be uniquely recovered sometimes, even without imposing any additional sparsity constraints. In this paper, we derive conditions under ...
Free energy computations by minimization of Kullback-Leibler divergence: an efficient adaptive biasing potential method for sparse representations
Free energy Kullback-Leibler divergence
2010/11/17
The present paper proposes an adaptive biasing potential for the computation of free energy landscapes. It is motivated by statistical learning arguments and unifies the tasks of biasing the molecula...

A High-Resolution Technique for Ultrasound Harmonic Imaging Using Sparse Representations in Gabor Frames
Gabor frames harmonic imaging sparse representations
2010/1/6
Over the last few decades there were dramatic
improvements in ultrasound imaging quality with the utilization
of harmonic frequencies induced by both tissue and echo-contrast
agents. The advantages...
