Metric Transforms and Low Rank Matrices via Representation Theory of the Real Hyperrectangle

Josh Alman, Timothy Chu, Gary Miller +3

In this paper, we develop a new technique which we call representation theory of the real hyperrectangle, which describes how to compute the eigenvectors and eigenvalues of certain…

Weighted Cheeger and Buser Inequalities, with Applications to Clustering and Cutting Probability Densities

Timothy Chu, Gary L. Miller, Noel J. Walkington +1

In this paper, we show how sparse or isoperimetric cuts of a probability density function relate to Cheeger cuts of its principal eigenfunction, for appropriate definitions of `spa…

Graph Sketching Against Adaptive Adversaries Applied to the Minimum Degree Algorithm

Matthew Fahrbach, Gary L. Miller, Richard Peng +3

Motivated by the study of matrix elimination orderings in combinatorial scientific computing, we utilize graph sketching and local sampling to give a data structure that provides a…

On Computing Min-Degree Elimination Orderings

Matthew Fahrbach, Gary L. Miller, Richard Peng +3

We study faster algorithms for producing the minimum degree ordering used to speed up Gaussian elimination. This ordering is based on viewing the non-zero elements of a symmetric p…

Exact Computation of a Manifold Metric, via Lipschitz Embeddings and Shortest Paths on a Graph

Timothy Chu, Gary Miller, Donald Sheehy

Data-sensitive metrics adapt distances locally based the density of data points with the goal of aligning distances and some notion of similarity. In this paper, we give the first…

An Empirical Study of Cycle Toggling Based Laplacian Solvers

Kevin Deweese, John R. Gilbert, Gary Miller +3

We study the performance of linear solvers for graph Laplacians based on the combinatorial cycle adjustment methodology proposed by [Kelner-Orecchia-Sidford-Zhu STOC-13]. The appro…
