Method Maximizing the Spread of Influence in Directed Signed Weighted Graphs [PDF]
Advances in Electrical and Electronic Engineering, 2017 We propose a new method for maximizing the spread of influence, based on the identification of significant factors of the total energy of a control system.

Weighted Modulo Orientations of Graphs and Signed Graphs [PDF]
The Electronic Journal of Combinatorics, 2022 Given a graph $G$ and an odd prime $p$, for a mapping $f: E(G) \to {\mathbb Z}_p\setminus\{0\}$ and a ${\mathbb Z}_p$-boundary $b$ of $G$, an orientation $\tau$ is called an $(f,b;p)$-orientation if the net out $f$-flow is the same as $b(v)$ in ${\mathbb Z}_p$ at each vertex $v\in V(G)$ under orientation $D$.

Inertias of Laplacian matrices of weighted signed graphs [PDF]
Special Matrices, 2019 We study the sets of inertias achieved by Laplacian matrices of weighted signed graphs. First we characterize signed graphs with a unique Laplacian inertia.

wsGAT: Weighted and Signed Graph Attention Networks for Link Prediction [PDF]
, 2022 Graph Neural Networks (GNNs) have been widely used to learn representations on graphs and tackle many real-world problems from a wide range of domains. In this paper we propose wsGAT, an extension of the Graph Attention Network (GAT) layers, meant to address the lack of GNNs that can handle graphs with signed and weighted links, which are ubiquitous ...

Nonlinear Merging Consensus for Multi-Agent Systems on Directed and Weighted Signed Graph [PDF]
IEEE Access, 2020 This paper settles the nonlinear merging consensus for multi-agent systems on a directed and weighted signed network. A novel nonlinear merging control protocol is proposed to drive the states of all agents to arrive at the same state. To be consistent with the reality, the interactions among agents can be either cooperative or competitive and the ...

BioengineeringThe early detection of Alzheimer’s disease (AD) is important for effective therapeutic interventions and optimized enrollment for clinical trials. Recent studies have shown high accuracy in identifying mild AD by applying visibility graph and machine learning methods to electroencephalographic (EEG) data.

K-Partitioning of Signed or Weighted Bipartite Graphs [PDF]
, 2013 — In this work, K-partitioning of signed or weighted bipartite graph problem has been introduced, which appears as a real life problem where the partitions of bipartite graph represent two different entities and the edges between the nodes of the ...

Polarization and multiscale structural balance in signed networks
Communications Physics, 2023 Polarization, or a division into mutually hostile groups, is a common feature of social systems. It is studied in Structural Balance Theory in terms of semicycles in signed networks.
