Neuroscience needs Network Science

no code implementations10 May 2023 Dániel L Barabási, Ginestra Bianconi, Ed Bullmore, Mark Burgess, SueYeon Chung, Tina Eliassi-Rad, Dileep George, István A. Kovács, Hernán Makse, Christos Papadimitriou, Thomas E. Nichols, Olaf Sporns, Kim Stachenfeld, Zoltán Toroczkai, Emma K. Towlson, Anthony M Zador, Hongkui Zeng, Albert-László Barabási, Amy Bernard, György Buzsáki

We explore the challenges and opportunities in integrating multiple data streams for understanding the neural transitions from development to healthy function to disease, and discuss the potential for collaboration between network science and neuroscience communities.

Persistent Dirac for molecular representation

no code implementations5 Feb 2023 JunJie Wee, Ginestra Bianconi, Kelin Xia

A series of physical persistent attributes, which characterize the spectrum of the Dirac matrices across a filtration, are proposed and used as efficient molecular fingerprints.

Dirac signal processing of higher-order topological signals

no code implementations12 Jan 2023 Lucille Calmon, Michael T. Schaub, Ginestra Bianconi

We discuss in detail the properties of the Dirac operator including its spectrum and the chirality of its eigenvectors and we adopt this operator to formulate Dirac signal processing that can filter noisy signals defined on nodes, links and triangles of simplicial complexes.

Local topological moves determine global diffusion properties of hyperbolic higher-order networks

no code implementations25 Feb 2021 Ana P Millán, Reza Ghorbanchian, Nicolò Defenu, Federico Battiston, Ginestra Bianconi

In this perspective, the spectral dimension plays a key role since it determines the effective dimension for diffusion processes on a network.

Universal nonlinear infection kernel from heterogeneous exposure on higher-order networks

1 code implementation18 Jan 2021 Guillaume St-Onge, Hanlin Sun, Antoine Allard, Laurent Hébert-Dufresne, Ginestra Bianconi

The colocation of individuals in different environments is an important prerequisite for exposure to infectious diseases on a social network.

Beyond COVID-19: Network science and sustainable exit strategies

no code implementations27 Sep 2020 James Bell, Ginestra Bianconi, David Butler, Jon Crowcroft, Paul C. W Davies, Chris Hicks, Hyunju Kim, Istvan Z. Kiss, Francesco Di Lauro, Carsten Maple, Ayan Paul, Mikhail Prokopenko, Philip Tee, Sara I. Walker

On May $28^{th}$ and $29^{th}$, a two day workshop was held virtually, facilitated by the Beyond Center at ASU and Moogsoft Inc.

The spectral dimension of simplicial complexes: a renormalization group theory

no code implementations28 Oct 2019 Ginestra Bianconi, Sergey N. Dorogovtsev

Simplicial complexes are increasingly used to study complex system structure and dynamics including diffusion, synchronization and epidemic spreading.

Classical Information Theory of Networks

no code implementations10 Aug 2019 Filippo Radicchi, Dmitri Krioukov, Harrison Hartle, Ginestra Bianconi

Existing information-theoretic frameworks based on maximum entropy network ensembles are not able to explain the emergence of heterogeneity in complex networks.

Machine learning meets network science: dimensionality reduction for fast and efficient embedding of networks in the hyperbolic space

no code implementations21 Feb 2016 Josephine Maria Thomas, Alessandro Muscoloni, Sara Ciucci, Ginestra Bianconi, Carlo Vittorio Cannistraci

Complex network topologies and hyperbolic geometry seem specularly connected, and one of the most fascinating and challenging problems of recent complex network theory is to map a given network to its hyperbolic space.
