"WebApr 26, 2012 · Let G be a graph with n vertices and m edges. A sparsifier of G is a sparse graph on the same vertex set approximating G in some natural way. It allows us to say useful things about G while considering much fewer than m edges. The strongest commonly-used notion of sparsification is spectral sparsification; H is a spectral … " - Graph sparsification by effective resistances

Graph Sparsification I: Sparsification via Effective Resistances

WebAbstract. We present a general framework for constructing cut sparsifiers in undirected graphs---weighted subgraphs for which every cut has the same weight as the original graph, up to a multiplicative factor of ( 1 ± ϵ). Using this framework, we simplify, unify, and improve upon previous sparsification results.

WebMay 6, 2024 · Sampling with Effective Resistance. The main idea is that for a given Stochastic Block Model (SBM) we know when we can recover the communities based on the parameters a, b of the model. While it is sometimes assumed that these parameters are known, Mossel et al. [] gives Eq. () for recovering the parameters of an unknown SBM, … WebMay 10, 2024 · Abstract. In this paper, we draw on Spielman and Srivastava’s method for graph sparsification in order to simplify shape representations. The underlying principle of graph sparsification is to retain only the edges which are key to the preservation of desired properties. In this regard, sparsification by edge resistance allows us to preserve ...
