Analysis of Sparse Subspace Clustering: Experiments and Random Projection
Mehmet F. Demirel, Enrico Au-Yeung
Clustering can be defined as the process of assembling objects into a number of groups whose elements are similar to each other in some manner. As a technique that is used in many…
Wind-tree model for billiard motion from a signal processing viewpoint
Enrico Au-Yeung, Nick Kreissler
In the Ehrenfest wind tree model, a point particle moves on the plane and collides with randomly placed fixed square obstacles under the usual law of geometric optics. The particle…
Phase Transition in the Recovery of Rank One Matrices Corrupted by Gaussian Noise
Enrico Au-Yeung, Greg Zanotti
In datasets where the number of parameters is fixed and the number of samples is large, principal component analysis (PCA) is a powerful dimension reduction tool. However, in many…
Sparse Reconstruction with Multiple Walsh matrices
Enrico Au-Yeung
The problem of how to find a sparse representation of a signal is an important one in applied and computational harmonic analysis. It is closely related to the problem of how to re…
Generalized Fourier frames in terms of balayage
Enrico Au-Yeung, John J. Benedetto
Based on Beurling's theory of balayage, we develop the theory of non-uniform sampling in the context of the theory of frames for the settings of the Short Time Fourier Transform an…
Balayage and Short time Fourier transform frames
Enrico Au-Yeung, John J. Benedetto
Using his formulation of the potential theoretic notion of balayage and his deep results about this idea, Beurling gave sufficient conditions for Fourier frames in terms of balayag…
Signal recovery and frames that are robust to erasure
Enrico Au-Yeung
We consider finite frames with high redundancy so that if half the terms transmitted from the sender are randomly deleted during transmission, then on average, the receiver can sti…
Tight frames, partial isometries, and signal reconstruction
Enrico Au-Yeung, Somantika Datta
This article gives a procedure to convert a frame which is not a tight frame into a Parseval frame for the same space, with the requirement that each element in the resulting Parse…
