A copula based topology preserving graph convolution network for clustering of single-cell RNA-seq data.

open access: yesPLoS Computational Biology, 2022
Annotation of cells in single-cell clustering requires a homogeneous grouping of cell populations. There are various issues in single cell sequencing that effect homogeneous grouping (clustering) of cells, such as small amount of starting RNA, limited ...

Sampling clustering based on multi-view attribute structural relations.

open access: yesPLoS ONE
In light of the exponential growth in information volume, the significance of graph data has intensified. Graph clustering plays a pivotal role in graph data processing by jointly modeling the graph structure and node attributes.

Three-Way Decision-Driven Adaptive Graph Convolution for Deep Clustering

open access: yesApplied Sciences
Graph clustering is an efficient method for deep clustering that utilizes graph convolution. Graph convolution effectively combines structure and content information, and lots of recent graph convolution-based methods have shown promising results in ...

A parameter-free graph reduction for spectral clustering and SpectralNet

open access: yesArray, 2022
Graph-based clustering methods like spectral clustering and SpectralNet are very efficient in detecting clusters of non-convex shapes. Unlike the popular k-means, graph-based clustering methods do not assume that each cluster has a single mean.

Generalized Graph Clustering: Recognizing (p,q)-Cluster Graphs [PDF]

open access: yes, 2010
CLUSTER EDITING is a classical graph theoretic approach to tackle the problem of data set clustering: it consists of modifying a similarity graph into a disjoint union of cliques, i.e, clusters. As pointed out in a number of recent papers, the cluster editing model is too rigid to capture common features of real data sets.

Partitioning Well-Clustered Graphs: Spectral Clustering Works! [PDF]

open access: yesSIAM Journal on Computing, 2017
In this paper we study variants of the widely used spectral clustering that partitions a graph into k clusters by (1) embedding the vertices of a graph into a low-dimensional space using the bottom eigenvectors of the Laplacian matrix, and (2) grouping the embedded points into k clusters via k-means algorithms. We show that, for a wide class of graphs,

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 ...
