The k-nearest neighbor graph is partitioned into several relatively small sub-clusters using a graph partitioning algorithm in such a way as to minimize the weight of the edges to be cut. The clustering eliminates edges whose vertices are not within the k closest points concerning each other ...
spectral graph partitioning and clustering relies on thespectrum—the eigenvalues and associated eigenvectors—of the Laplacian matrix corresponding to a given graph. Next, I will formally define this problem, show how it is related to the spectrum of...
Graph clustering is a form ofgraph miningthat is useful in a number ofpractical applications including marketing, customer segmentation, congestiondetection, facility location, and XML data integration (Lee, Hsu, Yang, &Yang,2002). The graph clustering problems are typically defined into twocategories...
The KVV algorithm is an improvement over the SM algorithm with the KVV algorithm using Cheeger conductance for partitioning. Calculating the Cheeger conductance is beneficial in the context of graph partitioning and clustering because it provides a quantitative measure of the quality of a graph cut [...
(10) 聚类(clustering) 一个超图的clustering C=\{C_1,...,C_l\} 是其顶点集合的分区。 与k-way分区相对,簇(clusters)的数量不会预先提供。并且对于 C_i 的实际大小不施加平衡限制。 (11) k-way hypergraph edge partitioning (k路超图边分区) 一个H 的k-way超图边分区是将其超边集合分区到 k 个...
2. RELATED WORK Graph partitioning has a rich history. It encompasses many problems and has many proposed solutions, from the very simple to the very sophisticated. We cannot hope to cover the whole field and will only focus on the most relevant formulation - balanced k-partitioning. The goal...

His graph partitioning algorithms – KaHIP – have been able to improve or reproduce most of the benchmark entries in the Walshaw Benchmark and scored most of the points in the 10th DIMACS Implementation Challenge on Graph Partitioning and Clustering....
Nonconvex graph learning: sparsity, heavy tails, and clustering 16.1.1 Learning undirected graphs An undirected, weighted graph is denoted as a triple G=(V,E,W), where V={1,2,…,p} is the node set, E⊆{{u,v}:u,v∈V,u≠v} is the edge set, that is, a subset of the set...
