Polarization and multiscale structural balance in signed networks [PDF]

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.

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.

Inertias of Laplacian matrices of weighted signed graphs

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.

Efficient Minus and Signed Domination in Proper Interval Graphs with a Totally Unimodular Structure

Axioms
The efficient minus domination problem (EMDP) and the efficient signed domination problem (ESDP) are domination-type problems in graphs. These problems are known to be NP-complete on chordal graphs and polynomially solvable on chain interval graphs ...

Task complexity shapes internal representations and robustness in neural networks

Machine Learning: Science and Technology
Neural networks excel across a wide range of tasks, yet remain ‘black boxes’. In particular, how their internal representations are shaped by the complexity of the input data and the problems they solve remains obscure. In this work, we introduce a suite
