Random graph matching at Otter's threshold via counting chandeliers

no code implementations25 Sep 2022 Cheng Mao, Yihong Wu, Jiaming Xu, Sophie H. Yu

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.

Testing network correlation efficiently via counting trees

no code implementations22 Oct 2021 Cheng Mao, Yihong Wu, Jiaming Xu, Sophie H. Yu

We propose a new procedure for testing whether two networks are edge-correlated through some latent vertex correspondence.

Settling the Sharp Reconstruction Thresholds of Random Graph Matching

no code implementations29 Jan 2021 Yihong Wu, Jiaming Xu, Sophie H. Yu

This paper studies the problem of recovering the hidden vertex correspondence between two edge-correlated random graphs.

no code implementations23 Aug 2020 Yihong Wu, Jiaming Xu, Sophie H. Yu

We study the problem of detecting the edge correlation between two random graphs with $n$ unlabeled nodes.
