Multi-view Attributed Graph Clustering Based on Contrast Consensus Graph Learning [PDF]

open access: yesJisuanji kexue
Multi-view attribute graph clustering can divide nodes of graph data with multiple views into different clusters,which has attracted widespread attention from researchers in recent years.At present,many multi-view attribute graph clustering me-thods ...

Cluster-Guided Contrastive Graph Clustering Network

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2023
Benefiting from the intrinsic supervision information exploitation capability, contrastive learning has achieved promising performance in the field of deep graph clustering recently. However, we observe that two drawbacks of the positive and negative sample construction mechanisms limit the performance of existing algorithms from further improvement. 1)

Random Graphs with Clustering [PDF]

open access: yesPhysical Review Letters, 2009
We offer a solution to a long-standing problem in the physics of networks, the creation of a plausible, solvable model of a network that displays clustering or transitivity -- the propensity for two neighbors of a network node also to be neighbors of one another.

Randomized graph cluster randomization

open access: yesJournal of Causal Inference, 2023
Abstract The global average treatment effect (GATE) is a primary quantity of interest in the study of causal inference under network interference. With a correctly specified exposure model of the interference, the Horvitz–Thompson (HT) and Hájek estimators of the GATE are unbiased and consistent, respectively, yet known to exhibit ...

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 ...

Graph-based data clustering via multiscale community detection

open access: yesApplied Network Science, 2020
We present a graph-theoretical approach to data clustering, which combines the creation of a graph from the data with Markov Stability, a multiscale community detection framework. We show how the multiscale capabilities of the method allow the estimation

Graph Clustering with Graph Neural Networks

open access: yes, 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.
