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…

The Algorithmic Phase Transition of Random Graph Alignment Problem
Hang Du, Shuyang Gong, Rundong Huang
We study the graph alignment problem over two independent ErdÅs-Rényi graphs on vertices, with edge density falling into two regimes separated by the critical window arou…
