Clustering Uncertain Graphs [PDF]

open access: greenProceedings of the VLDB Endowment, 2016
An uncertain graph 𝒢 = (V, E, p : E → (0, 1]) can be viewed as a probability space whose outcomes (referred to as possible worlds ) are subgraphs of 𝒢 where any edge e ε E occurs with probability p

Graph Contrastive Clustering [PDF]

open access: yes2021 IEEE/CVF International Conference on Computer Vision (ICCV), 2021
Recently, some contrastive learning methods have been proposed to simultaneously learn representations and clustering assignments, achieving significant improvements. However, these methods do not take the category information and clustering objective into consideration, thus the learned representations are not optimal for clustering and the ...

Bounded graph clustering with graph neural networks

open access: yesJournal of Physics: Complexity
In community detection, many methods require the user to specify the number of clusters in advance since an exhaustive search over all possible values is computationally infeasible.

AutoGraph: Autonomous Graph Based Clustering of Small-Molecule Conformations

open access: green, 2020
While accurately modeling the conformational ensemble is required for predicting properties of flexible molecules, the optimal method of obtaining the conformational ensemble seems as varied as their applications.

A graph clustering algorithm based on a clustering coefficient for weighted graphs [PDF]

open access: yesJournal of the Brazilian Computer Society, 2010
Abstract Graph clustering is an important issue for several applications associated with data analysis in graphs. However, the discovery of groups of highly connected nodes that can represent clusters is not an easy task. Many assumptions like the number of clusters and if the clusters are or not balanced, may need to be made before the ...

Clustering sequence graphs

open access: yesData & Knowledge Engineering, 2022
In application domains ranging from social networks to e-commerce, it is important to cluster users with respect to both their relationships (e.g., friendship or trust) and their actions (e.g., visited locations or rated products). Motivated by these applications, we introduce here the task of clustering the nodes of a sequence graph, i.e., a graph ...

Graph Clustering with Graph Neural Networks

open access: yesJ. Mach. Learn. Res., 2020
Graph Neural Networks (GNNs) have achieved state-of-the-art results on many graph analysis tasks such as node classification and link prediction. However, important unsupervised problems on graphs, such as graph clustering, have proved more resistant to advances in GNNs.

Contrastive and attentive graph learning for multi-view clustering

open access: yes, 2022
Graph-based multi-view clustering aims to take advantage of multiple view graph information to provide clustering solutions. The consistency constraint of multiple views is the key of multi-view graph clustering.

A survey of kernel and spectral methods for clustering [PDF]

open access: yes, 2007
Clustering algorithms are a useful tool to explore data structures and have been employed in many disciplines. The focus of this paper is the partitioning clustering problem with a special interest in two recent approaches: kernel and spectral methods ...
