Graph Clustering using Effective Resistance [article]

Vedat Levi Alev, Nima Anari, Lap Chi Lau, Shayan Oveis Gharan
2017 arXiv   pre-print
δ^-1 fraction of the weights are between clusters, i.e. w(E - ∪_i = 1^h E(V_i)) ≲w(E)/δ; ∙ the effective resistance diameter of each of the induced subgraphs G[V_i] is at most δ^3 times the average weighted  ...  This implies that very mildly expanding graphs have constant effective resistance diameter. We believe that this connection could be of independent interest in algorithm design.  ...  Acknowledgements We would like to thank Hong Zhou for helpful discussions and anonymous referees for their useful suggestions.  ...

Fast Community Detection with Graph Sparsification [chapter]

Jesse Laeuchli
2020 Lecture Notes in Computer Science  
A popular approach is to use spectral methods where the Graph Laplacian L of the given graph is created, and the Fiedler vector of the graph is found.  ...  This vector is then used to cluster nodes in the same community. While a robust method, it can be expensive to compute the Fiedler vector exactly.  ...  Conclusion and Future Work In this paper we explored the use of sparsifying by effective resistance and scaled effective resistances in order to recover sparsify SBMs, as well as effective stopping criteria  ...
