The impact of the path ensemble on path percolation
Yunhao Ding, Andreas Münch, Renaud Lambiotte
Traffic-induced failures, from packet loss in communication networks to congestion breakdown in transport systems, occur when flows progressively exhaust the edges they traverse. P…
From First Principles to Multi-scale Decomposition:Mutual Information as a Segregation Index
Rohit Sahasrabuddhe, Renaud Lambiotte
Segregation is a multi-scale phenomenon that requires careful measurement. A segregation index implicitly defines how the demographic compositions of locations are compared. We ide…
Modeling Urban Air Quality Using Taxis as Sensors
Anastasios Noulas, Yasin Acikmese, Charles QC LI +5
Monitoring urban air quality with high spatiotemporal resolution continues to pose significant challenges. We investigate the use of taxi fleets as mobile sensing platforms, analyz…
Concise network models of memory dynamics reveal explainable patterns in path data
Rohit Sahasrabuddhe, Renaud Lambiotte, Martin Rosvall
Networks are a powerful tool to model the structure and dynamics of complex systems across scales. Direct connections between system components are often represented as edges, whil…
Garbage in Garbage out: Impacts of data quality on criminal network intervention
Wang Ngai Yeung, Riccardo Di Clemente, Renaud Lambiotte
Criminal networks such as human trafficking rings are threats to the rule of law, democracy and public safety in our global society. Network science provides invaluable tools to id…
Dynamic models of gentrification
Giovanni Mauro, Nicola Pedreschi, Renaud Lambiotte +1
The phenomenon of gentrification of an urban area is characterized by the displacement of lower-income residents due to rising living costs and an influx of wealthier individuals.…
Detection of anomalous spatio-temporal patterns of app traffic in response to catastrophic events
Sofia Medina, Shazia'Ayn Babul, Rohit Sahasrabuddhe +3
In this work, we uncover patterns of usage mobile phone applications and information spread in response to perturbations caused by unprecedented events. We focus on categorizing pa…
Strong and Weak Random Walks on Signed Networks
Shazia'Ayn Babul, Yu Tian, Renaud Lambiotte
Random walks play an important role in probing the structure of complex networks. On traditional networks, they can be used to extract community structure, understand node centrali…
The Role of Second Trials in Cascades of Information over Networks
C. de Kerchove, G. Krings, R. Lambiotte +2
We study the propagation of information in social networks. To do so, we focus on a cascade model where nodes are infected with {probability after their first contact with th…
Andrzej Pekalski networks of scientific interests with internal degrees of freedom through self-citation analysis
M. Ausloos, R. Lambiotte, A. Scharnhorst +1
Old and recent theoretical works by Andrzej Pekalski (APE) are recalled as possible sources of interest for describing network formation and clustering in complex (scientific) comm…
Dynamics of Vacillating Voters
R. Lambiotte, S. Redner
We introduce the vacillating voter model in which each voter consults two neighbors to decide its state, and changes opinion if it disagrees with either neighbor. This irresolution…
Activity ageing in growing networks
R. Lambiotte
We present a model for growing information networks where the ageing of a node depends on the time at which it entered the network and on the last time it was cited. The model is s…
How does degree heterogeneity affect an order-disorder transition?
R. Lambiotte
We focus on the role played by the node degree distribution on the way collective phenomena emerge on complex networks. To address this question, we focus analytically on a typical…
Growing network with j-redirection
R. Lambiotte, M. Ausloos
A model for growing information networks is introduced where nodes receive new links through j-redirection, i.e. the probability for a node to receive a link depends on the number…
Clusters or networks of economies? A macroeconomy study through GDP fluctuation correlations
M. Ausloos, R. Lambiotte
We follow up on the study of correlations between GDP's of rich countries. We analyze web-downloaded data on GDP that we use as individual wealth signatures of the country economic…
