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 …

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

J Gaudio, MZ Racz, A Sridhar - Conference on Learning …, 2022 - proceedings.mlr.press
We consider the problem of learning latent community structure from multiple correlated
networks. We study edge-correlated stochastic block models with two balanced …

The problem of detecting edge correlation between two Erdős-Rényi random graphs on
unlabeled nodes can be formulated as a hypothesis testing problem: under the null …

Low-Degree Hardness of Detection for Correlated Erd\H {o} sR\'enyi Graphs

J Ding, H Du, Z Li - arXiv preprint arXiv:2311.15931, 2023 - arxiv.org
Given two Erd\H {o} sR\'enyi graphs with $ n $ vertices whose edges are correlated through
a latent vertex correspondence, we study complexity lower bounds for the associated …

Aligning random graphs with a sub-tree similarity message-passing algorithm

G Piccioli, G Semerjian, G Sicuro… - Journal of Statistical …, 2022 - iopscience.iop.org
The problem of aligning Erdős–Rényi random graphs is a noisy, average-case version of the
graph isomorphism problem, in which a pair of correlated random graphs is observed …

One-way matching of datasets with low rank signals

S Chen, S Jiang, Z Ma, GP Nolan, B Zhu - arXiv preprint arXiv:2204.13858, 2022 - arxiv.org
We study one-way matching of a pair of datasets with low rank signals. Under a stylized
model, we first derive information-theoretic limits of matching under a mismatch proportion …

A polynomial‐time approximation scheme for the maximal overlap of two independent Erdős–Rényi graphs

J Ding, H Du, S Gong - Random Structures & Algorithms, 2024 - Wiley Online Library
For two independent Erdős–Rényi graphs G (n, p) G\left (n, p\right), we study the maximal
overlap (ie, the number of common edges) of these two graphs over all possible vertex …
