The extension of the proposed model to signed graph translation A variant of the proposed model called sign-NEC-DGT is designed by proposing a novel signed spectral-based regularization, which is based on a specially designed definition of graph Laplacian for signed networks. The extension of the...
Furthermore, when the signed graph does not satisfy the structurally-balanced condition, via Laplacian matrix decomposition, the BSQS of QVNNs with structurally-unbalanced graphs under deception attacks is investigated. Notable contributions are listed as below: The subsequent sections of this work are...

Figure 6b shows a plot of the generated node position versus the position determined by the first eigenvector for a well-ordered synthetic graph with 100 nodes and threshold = 0.1. Unlike the opposing Laplacian and SPONGE, the SHEEP embedding recovers the initial node ordering. We test ...
,xnT(t)]T∈Rdn and L is the matrix-valued graph Laplacian. Definition 3 Bipartite Consensus The multi-agent network (1) is said to admit a bipartite consensus Balancing set of matrix-weighted networks A prominent structural feature of the edge we studied in Example 1 concerns its negation ...
Leader-follower controllability in brain networks which are affected neurodegenerative diseases can provide important biomarkers relevant for disease evolution. The brain network is viewed as a dynamic system where the nodes interact via neighbor-based Laplacian feedback rules. The network has cooperative ...
Graph theoretic properties of the asymmetric, weighted, and signed connectome In the previous section, we explored the modular architecture of the newly derived asymmetric, weighted, and signed matrix, comparing it with analogous measures made on the fiber density matrix. Modular structure, however, ...

For a signed directed graph 𝒢G that meets the condition in Definition 1, define 𝐋𝐆=𝐋+𝐆LG=L+G. In the following, we will introduce the notation for signed digraphs and elaborate on the relationship between the Laplacian matrix and signed graphs. A signed digraph 𝐺=(𝑉,𝐸...
