Local higher-order graph clustering

H Yin, AR Benson, J Leskovec, DF Gleich - Proceedings of the 23rd ACM …, 2017 - dl.acm.org
Local graph clustering methods aim to find a cluster of nodes by exploring a small region of
the graph. These methods are attractive because they enable targeted clustering around a …

Heat kernel based community detection

K Kloster, DF Gleich - Proceedings of the 20th ACM SIGKDD …, 2014 - dl.acm.org
The heat kernel is a type of graph diffusion that, like the much-used personalized PageRank
diffusion, is useful in identifying a community nearby a starting seed node. We present the …

Partitioning well-clustered graphs: Spectral clustering works!

R Peng, H Sun, L Zanetti - Conference on learning theory, 2015 - proceedings.mlr.press
In this work we study the widely used\emphspectral clustering algorithms, ie partition a
graph into k clusters via (1) embedding the vertices of a graph into a low-dimensional space …

A tighter analysis of spectral clustering, and beyond

P Macgregor, H Sun - International Conference on Machine …, 2022 - proceedings.mlr.press
This work studies the classical spectral clustering algorithm which embeds the vertices of
some graph G=(V_G, E_G) into R^ k using k eigenvectors of some matrix of G, and applies k …

Local flow partitioning for faster edge connectivity

M Henzinger, S Rao, D Wang - SIAM Journal on Computing, 2020 - SIAM
We study the problem of computing a minimum cut in a simple, undirected graph and give a
deterministic O(m\log^2n\log\log^2n) time algorithm. This improves on both the best …

Flow-based algorithms for local graph clustering

L Orecchia, ZA Zhu - Proceedings of the twenty-fifth annual ACM-SIAM …, 2014 - SIAM
Given a subset A of vertices of an undirected graph G, the cut-improvement problem asks us
to find a subset S that is similar to A but has smaller conductance. An elegant algorithm for …

Bear: Block elimination approach for random walk with restart on large graphs

K Shin, J Jung, S Lee, U Kang - Proceedings of the 2015 ACM SIGMOD …, 2015 - dl.acm.org
Given a large graph, how can we calculate the relevance between nodes fast and
accurately? Random walk with restart (RWR) provides a good measure for this purpose and …
