Improved $ℓ_{0}$ -Isoperimetry for Convex Bodies via Mass Transport

Manuel Fernandez

We study $ℓ_{0}$ isoperimetry for a convex body $K \subset R^{n}$ , $n \geq 2$ . For a Borel set $S \subset K$ , let $\partial_{0}^{K} S$ be the set of points in $K ∖ S$ that c…

Spectral Concentration and Recovery in Sparse High-Dimensional Random Geometric Graphs

Manuel Fernandez, Yizhe Zhu

We study sparse threshold random geometric graphs generated by high-dimensional spherical or Gaussian latent vectors. Although each edge has marginal probability $p$ , shared latent…

Achieving the Kesten-Stigum bound in the non-uniform hypergraph stochastic block model

Manuel Fernandez, Ludovic Stephan, Yizhe Zhu

We study the community detection problem in the non-uniform hypergraph stochastic block model (HSBM), where hyperedges of varying sizes coexist. This setting captures higher-order…
