Optimal Thresholds for Monotone Non-Boolean Functions
Saba Lepsveridze, Allen Lin
Let , let denote the simplex of probability measures on , and let denote the Lebesgue measure normalized on . We prove that for a…
Optimal Spectral Algorithms for Correlated Two-view Models in High Dimensions
Hang Du, Henry Hu, Saba Lepsveridze
We study high-dimensional inference in correlated two-view models, focusing on spectral methods for strong detection and weak recovery. We introduce a general framework, motivated…
Uniform Geodesic Drawings of Graphs
Saba Lepsveridze, Oriol Solé-Pi
We study crossing numbers of dense graph drawings whose vertices are uniformly distributed either on the unit sphere or in a compact convex planar domain. We prove a sharp inequali…
Sharp Threshold for the Convergence of Nonstationary Averaging
Saba Lepsveridze, Elchanan Mossel
We study non-stationary averaging processes, where each term of a sequence is a weighted average of previous terms, namely . Our results extend c…
Size of the largest sum-free subset of and
Saba Lepsveridze, Yihang Sun
We determine the density of the largest sum-free subset of the lattice cube for and . This solves a conjecture of Cameron and Aydinian in dime…
