A Hierarchical Parallel Graph Summarization Approach Based on Ranking Nodes

open access: yesApplied Sciences, 2023
Graph summarization techniques are vital in simplifying and extracting enormous quantities of graph data. Traditional static graph structure-based summarization algorithms generally follow a minimum description length (MDL) style, and concentrate on ...

Deeper Exploiting Graph Structure Information by Discrete Ricci Curvature in a Graph Transformer

open access: yesEntropy, 2023
Graph-structured data, operating as an abstraction of data containing nodes and interactions between nodes, is pervasive in the real world. There are numerous ways dedicated to extract graph structure information explicitly or implicitly, but whether it ...

Leader Election for Anonymous Asynchronous Agents in Arbitrary Networks [PDF]

open access: yes, 2012
We study the problem of leader election among mobile agents operating in an arbitrary network modeled as an undirected graph. Nodes of the network are unlabeled and all agents are identical.

Symmetry in complex unit gain graphs and their spectra

open access: hybridLinear Algebra and its Applications
Complex unit gain graphs may exhibit various kinds of symmetry. In this work, we explore structural symmetry, spectral symmetry and sign-symmetry in such graphs, and their respective relations to one-another. Our main result is a construction that transforms an arbitrary complex unit gain graph into infinitely many switching-distinct ones whose ...

Feature-Enhanced Latent Summarization Model of Heterogeneous Network [PDF]

open access: yesJisuanji kexue yu tansuo, 2022
With the rapid growth of network data, large-scale heterogeneous network data storage and network repre-sentation have become hot research topics. This paper proposes two different tasks, generating graph summarization and generating node representations

Bayesian graph edit distance [PDF]

open access: yes, 2000
This paper describes a novel framework for comparing and matching corrupted relational graphs. The paper develops the idea of edit-distance originally introduced for graph-matching by Sanfeliu and Fu [1].

Promise and Limitations of Supervised Optimal Transport-Based Graph Summarization via Information Theoretic Measures

open access: yesIEEE Access, 2023
Graph summarization is the problem of producing smaller graph representations of an input graph dataset, in such a way that the smaller compressed graphs capture relevant structural information for downstream tasks.

Interconnected Observers for Robust Decentralized Estimation with Performance Guarantees and Optimized Connectivity Graph [PDF]

open access: yes, 2015
Motivated by the need of observers that are both robust to disturbances and guarantee fast convergence to zero of the estimation error, we propose an observer for linear time-invariant systems with noisy output that consists of the combination of N ...

Balance in gain graphs – A spectral analysis

open access: yesLinear Algebra and its Applications, 2012
AbstractA gain graph is a graph where the edges are given some orientation and labeled with the elements (called gains) from a group so that gains are inverted when we reverse the direction of the edges. A signed graph with labels from the multiplicative group {1,-1} on the edges can be taken as a particular case of a gain graph.
