The eigenvalues and eigenvectors of finite, low rank perturbations of large random matrices

F Benaych-Georges, RR Nadakuditi - Advances in Mathematics, 2011 - Elsevier
We consider the eigenvalues and eigenvectors of finite, low rank perturbations of random
matrices. Specifically, we prove almost sure convergence of the extreme eigenvalues and …

The wasteland of random supergravities

D Marsh, L McAllister, T Wrase - Journal of high energy physics, 2012 - Springer
A bstract We show that in a general\(\mathcal {N}={1}\) supergravity with N≫ 1 scalar fields,
an exponentially small fraction of the de Sitter critical points are metastable vacua. Taking …

Spectra of random graphs with arbitrary expected degrees

RR Nadakuditi, MEJ Newman - Physical Review E—Statistical, Nonlinear, and …, 2013 - APS
We study random graphs with arbitrary distributions of expected degree and derive
expressions for the spectra of their adjacency and modularity matrices. We give a complete …

Asymptotic performance of PCA for high-dimensional heteroscedastic data

D Hong, L Balzano, JA Fessler - Journal of multivariate analysis, 2018 - Elsevier
Abstract Principal Component Analysis (PCA) is a classical method for reducing the
dimensionality of data by projecting them onto a subspace that captures most of their …
