Mapping the Similarities of Spectra: Global and Locally-biased Approaches to SDSS Galaxy Data
David Lawlor, Tamás Budavári, Michael W. Mahoney
We apply a novel spectral graph technique, that of locally-biased semi-supervised eigenvectors, to study the diversity of galaxies. This technique permits us to characterize empiri…

A Multiscale Sub-linear Time Fourier Algorithm for Noisy Data
Andrew Christlieb, David Lawlor, Yang Wang
We extend the recent sparse Fourier transform algorithm of (Lawlor, Christlieb, and Wang, 2013) to the noisy setting, in which a signal of bandwidth N is given as a superposition o…

Adaptive sub-linear Fourier algorithms
David Lawlor, Yang Wang, Andrew Christlieb
We present a new deterministic algorithm for the sparse Fourier transform problem, in which we seek to identify k << N significant Fourier coefficients from a signal of bandwidth N…
