Title

Low-Rank Structured Matrix Reconstruction from Random Measurements

Abstract

I will present some results on low-rank Hankel and Toeplitz matrix reconstruction from random measurements. In particular, I will give the lower bound of number of random Gaussian measurements for exact low-rank Hankel and Toeplitz matrix reconstruction. This will be applied to spectral compressed sensing and NMR spectrascopy and compared with existing methods.
