Deep Neural Networks via Complex Network Theory: a Perspective

no code implementations17 Apr 2024 Emanuele La Malfa, Gabriele La Malfa, Giuseppe Nicosia, Vito Latora

For the novel metrics, in addition to the existing ones, we provide a mathematical formalisation for Fully Connected, AutoEncoder, Convolutional and Recurrent neural networks, of which we vary the activation functions and the number of hidden layers.

The importance of quality in austere times: University competitiveness and grant income

no code implementations26 Sep 2023 Ye Sun, Athen Ma, Georg von Graevenitz, Vito Latora

UK science funding agencies significantly reduced numbers of grants and total grant funding in response to austerity, but surprisingly restrictions of science funding were relaxed after the 2015 general election.

Deep Neural Networks as Complex Networks

no code implementations12 Sep 2022 Emanuele La Malfa, Gabriele La Malfa, Claudio Caprioli, Giuseppe Nicosia, Vito Latora

Deep Neural Networks are, from a physical perspective, graphs whose `links` and `vertices` iteratively process data and solve tasks sub-optimally.

MultiSAGE: a multiplex embedding algorithm for inter-layer link prediction

no code implementations24 Jun 2022 Luca Gallo, Vito Latora, Alfredo Pulvirenti

Here we propose MultiSAGE, a generalization of the GraphSAGE algorithm that allows to embed multiplex networks.

Artificial intelligence applied to bailout decisions in financial systemic risk management

no code implementations3 Feb 2021 Daniele Petrone, Neofytos Rodosthenous, Vito Latora

The underlying dynamics is derived from the network of financial institutions linked by mutual exposures, and the negative rewards are associated to the banks' default.

Control technique for synchronization of selected nodes in directed networks

no code implementations18 Jan 2021 Bruno Ursino, Lucia Valentina Gambuzza, Vito Latora, Mattia Frasca

Our proposed method is based on the introduction of distributed controllers that modify the topology of the connections in order to generate outer symmetries in the nodes to be controlled.

Interacting discovery processes on complex networks

1 code implementation11 Dec 2020 Iacopo Iacopini, Gabriele Di Bona, Enrico Ubaldi, Vittorio Loreto, Vito Latora

Innovation is the driving force of human progress.

Unified treatment of synchronization patterns in generalized networks with higher-order, multilayer, and temporal interactions

1 code implementation1 Oct 2020 Yuanzhao Zhang, Vito Latora, Adilson E. Motter

When describing complex interconnected systems, one often has to go beyond the standard network description to account for generalized interactions.

Evolutionary dynamics of higher-order interactions in social networks

no code implementations28 Jan 2020 Unai Alvarez-Rodriguez, Federico Battiston, Guilherme Ferraz de Arruda, Yamir Moreno, Matjaz Perc, Vito Latora

We live and cooperate in networks.

Simplicial models of social contagion

1 code implementation16 Oct 2018 Iacopo Iacopini, Giovanni Petri, Alain Barrat, Vito Latora

Complex networks have been successfully used to describe the spreading of a disease in populations of interacting individuals.

The multiplex dependency structure of financial markets

1 code implementation15 Jun 2016 Nicoló Musmeci, Vincenzo Nicosia, Tomaso Aste, Tiziana Di Matteo, Vito Latora

We propose here a multiplex network approach to investigate simultaneously different types of dependency in complex data sets.
