This paper studies the prescribed-time bipartite consensus problem for multiple Euler-Lagrange systems (MELSs) under directed matrix-weighted signed graph, in which input-to-output redundancy, external disturbances and uncertain dynamic terms have been taken into consideration. Firstly, this paper proposes the prescribed-time hierarchical control (PTHC)

Weighted Signed Graph (WSG) power-aware routing in distributed wireless networks
2012 IEEE Globecom Workshops, 2012In this paper, we propose a Weighted Signed Graph (WSG)-based power-aware routing scheme for distributed wireless networks. It is a practically implementable and self re-configurable distributed solution. It is an alternative and novel method to solve the constraint optimization with network lifetime and throughput in wireless networks.

GEE: Graphormer-Enhanced Encoder Model for Anomaly Detection in Weighted Signed Networks
IEEE International Conference on Systems, Man and CyberneticsComplex network structures with signed and weighted relationships are common in many real-world systems. We present Graphormer-Enhanced Encoder (GEE), a transformer-based model for anomaly detection in such graphs.

Quantum search of matching on signed graphs
Quantum Information Processing, 2020We construct a quantum searching model of a signed edge driven by a quantum walk. The time evolution operator of this quantum walk provides a weighted adjacency matrix induced by the assignment of a sign to each edge.

A bound on the rank of weighted graphs in terms of girth
Linear and multilinear algebraLet $ \tilde {\Phi }=(G,w) $ Φ~=(G,w) be a connected weighted graph and $ A(\tilde {\Phi }) $ A(Φ~) be its adjacency matrix. The rank $ r(G,w) $ r(G,w) of $ \tilde {\Phi } $ Φ~ is defined as the rank of its adjacency matrix $ A(\tilde {\Phi }) $ A(Φ ...

International Journal of Control
This work considers a signed, weighted, and directed multi-ensemble network operating on a heterogeneous first-order dynamics in n-dimensional state space. The communication topology is fixed and the time-scale is continuous. By classifying the ensembles

Controllability of Multi-Agent Systems over Signed Graphs
2019 14th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2019This work studies the controllability problem of multi-agent system over directed signed topology. The model we adopted is leader-follower system and some agents are chosen as leaders to control the rest of all the agents. The definition of sign-weighted-

Belief Graphs with Reasoning Zones: Structure, Dynamics, and Epistemic Activation
arXiv.orgBelief systems are rarely globally consistent, yet effective reasoning often persists locally. We propose a novel graph-theoretic framework that cleanly separates credibility--external, a priori trust in sources--from confidence--an internal, emergent ...

Link Analysis of Conflict through Signed Spectral Embedding: The Russo-Ukrainian War
2024 International Conference on Military Communication and Information Systems (ICMCIS)In military intelligence, link analysis is a tool used to review relationships between individuals or groups for insight. The difficulty of accurately depicting complex relationships in link diagrams increases as the number of actors and their activities
