Singular Values Versus Expansion in Directed and Undirected Graphs

Jake Ruotolo, Salil Vadhan

We relate the nontrivial singular values of the normalized adjacency matrix of an Eulerian directed graph to combinatorial measures of graph expansion: \\ 1. We in…

Securing Unbounded Differential Privacy Against Timing Attacks

Zachary Ratliff, Salil Vadhan

Recent works have started to theoretically investigate how we can protect differentially private programs against timing attacks, by making the joint distribution the output and th…

Sparsest cut and eigenvalue multiplicities on low degree Abelian Cayley graphs

Tommaso d'Orsi, Chris Jones, Jake Ruotolo +2

Whether or not the Sparsest Cut problem admits an efficient -approximation algorithm is a fundamental algorithmic question with connections to geometry and the Unique Games C…

Characterizing the Distinguishability of Product Distributions through Multicalibration

Cassandra Marcussen, Aaron Putterman, Salil Vadhan

Given a sequence of samples promised to be drawn from one of two distributions , a well-studied problem in statistics is to decide dis…
