On the use of Vision-Language models for Visual Sentiment Analysis: a study on CLIP
Cristina Bustos, Carles Civit, Brian Du +2
This work presents a study on how to exploit the CLIP embedding space to perform Visual Sentiment Analysis. We experiment with two architectures built on top of the CLIP embedding…
Explainable, automated urban interventions to improve pedestrian and vehicle safety
Cristina Bustos, Daniel Rhoads, Albert Sole-Ribalta +4
At the moment, urban mobility research and governmental initiatives are mostly focused on motor-related issues, e.g. the problems of congestion and pollution. And yet, we can not d…
Predicting Driver Self-Reported Stress by Analyzing the Road Scene
Cristina Bustos, Neska Elhaouij, Albert Sole-Ribalta +3
Several studies have shown the relevance of biosignals in driver stress recognition. In this work, we examine something important that has been less frequently explored: We develop…
Neutral Theory for competing attention in social networks
Carlos A. Plata, Emanuele Pigani, Sandro Azaele +6
We used an ecological approach based on a neutral model to study the competition for attention in an online social network. This novel approach allow us to analyze some ecological…
Online division of labour: emergent structures in Open Source Software
María J. Palazzi, Jordi Cabot, Javier Luis Cánovas Izquierdo +2
The development Open Source Software fundamentally depends on the participation and commitment of volunteer developers to progress. Several works have presented strategies to incre…
Antagonistic Structural Patterns in Complex Networks
María J. Palazzi, Javier Borge-Holthoefer, Claudio Tessone +1
Identifying and explaining the structure of complex networks at different scales has become an important problem across disciplines. At the mesoscale, modular architecture has attr…
Effect of shortest path multiplicity on congestion of multiplex networks
Albert Solé-Ribalta, Alex Arenas, Sergio Gómez
Shortest paths are representative of discrete geodesic distances in graphs, and many descriptors of networks depend on their counting. In multiplex networks, this counting is radic…
Revealing In-Block Nestedness: detection and benchmarking
Albert Solé-Ribalta, Claudio J. Tessone, Manuel S. Mariani +1
As new instances of nested organization --beyond ecological networks-- are discovered, scholars are debating around the co-existence of two apparently incompatible macroscale archi…
A model to identify urban traffic congestion hotspots in complex networks
Albert Solé-Ribalta, Sergio Gómez, Alex Arenas
Traffic congestion is one of the most notable problems arising in worldwide urban areas, importantly compromising human mobility and air quality. Current technologies to sense real…
Decongestion of urban areas with hotspot-pricing
Albert Solé-Ribalta, Sergio Gómez, Alex Arenas
The rapid growth of population in urban areas is jeopardizing the mobility and air quality worldwide. One of the most notable problems arising is that of traffic congestion which i…
Congestion induced by the structure of multiplex networks
Albert Solé-Ribalta, Sergio Gómez, Alex Arenas
Multiplex networks are representations of multilayer interconnected complex networks where the nodes are the same at every layer. They turn out to be good abstractions of the intri…
Information transfer in community structured multiplex networks
Albert Solé-Ribalta, Clara Granell, Sergio Gómez +1
The study of complex networks that account for different types of interactions has become a subject of interest in the last few years, specially because its representational power…
Random walk centrality in interconnected multilayer networks
Albert Solé-Ribalta, Manlio De Domenico, Sergio Gómez +1
Real-world complex systems exhibit multiple levels of relationships. In many cases they require to be modeled as interconnected multilayer networks, characterizing interactions of…
Centrality in Interconnected Multilayer Networks
Manlio De Domenico, Albert Solé-Ribalta, Elisa Omodei +2
Real-world complex systems exhibit multiple levels of relationships. In many cases, they require to be modeled by interconnected multilayer networks, characterizing interactions on…
Spectral properties of the Laplacian of multiplex networks
Albert Sole-Ribalta, Manlio De Domenico, Nikos E. Kouvaris +3
One of the more challenging tasks in the understanding of dynamical properties of models on top of complex networks is to capture the precise role of multiplex topologies. In a rec…
Structure of Triadic Relations in Multiplex Networks
Emanuele Cozzo, Mikko Kivelä, Manlio De Domenico +5
Recent advances in the study of networked systems have highlighted that our interconnected world is composed of networks that are coupled to each other through different "layers" t…
Mathematical Formulation of Multi-Layer Networks
Manlio De Domenico, Albert Solè-Ribalta, Emanuele Cozzo +5
A network representation is useful for describing the structure of a large variety of complex systems. However, most real and engineered systems have multiple subsystems and layers…
Random Walks on Multiplex Networks
M. De Domenico, A. Sole, S. Gomez +1
Multiplex networks are receiving increasing interests because they allow to model relationships between networked agents on several layers simultaneously. In this supplementary mat…
On the Relation Between the Common Labelling and the Median Graph
Nicola Rebagliati, Albert Solé-Ribalta, Marcello Pelillo +1
In structural pattern recognition, given a set of graphs, the computation of a Generalized Median Graph is a well known problem. Some methods approach the problem by assuming a rel…
