Random graph matching at Otter's threshold via counting chandeliers

C Mao, Y Wu, J Xu, SH Yu - Proceedings of the 55th Annual ACM …, 2023 - dl.acm.org
We propose an efficient algorithm for graph matching based on similarity scores constructed
from counting a certain family of weighted trees rooted at each vertex. For two Erdős–Rényi …

Correlated stochastic block models: Exact graph matching with applications to recovering communities

M Racz, A Sridhar - Advances in Neural Information …, 2021 - proceedings.neurips.cc
We consider the task of learning latent community structure from multiple correlated
networks. First, we study the problem of learning the latent vertex correspondence between …

Partial recovery in the graph alignment problem

G Hall, L Massoulié - Operations Research, 2023 - pubsonline.informs.org
In this paper, we consider the graph alignment problem, which is the problem of recovering,
given two graphs, a one-to-one mapping between nodes that maximizes edge overlap. This …

The algorithmic phase transition of random graph alignment problem

H Du, S Gong, R Huang - arXiv preprint arXiv:2307.06590, 2023 - arxiv.org
We study the graph alignment problem over two independent Erd\H {o} sR\'enyi graphs on $
n $ vertices, with edge density $ p $ falling into two regimes separated by the critical window …

Exact community recovery in correlated stochastic block models

We consider the problem of learning latent community structure from multiple correlated
networks. We study edge-correlated stochastic block models with two balanced …

Detection threshold for correlated Erdős-Rényi graphs via densest subgraph

J Ding, H Du - IEEE Transactions on Information Theory, 2023 - ieeexplore.ieee.org
The problem of detecting edge correlation between two Erdős-Rényi random graphs on

Statistical limits of correlation detection in trees

L Ganassali, L Massoulié… - The Annals of Applied …, 2024 - projecteuclid.org
