Franco Galante, Luca Vassio, Michele Garetto +1
The increasing popularity of online social networks (OSNs) attracted growing interest in modeling social interactions. On online social platforms, a few individuals, commonly refer…
Asynchronous semi-anonymous dynamics over large-scale networks
Chiara Ravazzi, Giacomo Como, Michele Garetto +2
We analyze a class of stochastic processes, referred to as asynchronous and semi-anonymous dynamics (ASD), over directed labeled random networks. These processes are a natural tool…
Opinion Dynamics on Correlated Subjects in Social Networks
Alessandro Nordio, Alberto Tarable, Carla Fabiana Chiasserini +1
Understanding the evolution of collective beliefs is of critical importance to get insights on the political trends as well as on social tastes and opinions. In particular, it is p…

Alessandro Nordio, Alberto Tarable, Carla Fabiana Chiasserini +1
The advent and proliferation of social media have led to the development of mathematical models describing the evolution of beliefs/opinions in an ecosystem composed of socially in…
Generalized threshold-based epidemics in random graphs: the power of extreme values
Michele Garetto, Emilio Leonardi, Giovanni Luca Torrisi
Bootstrap percolation is a well-known activation process in a graph, in which a node becomes active when it has at least active neighbors. Such process, originally studied on r…
Impact of Clustering on the Performance of Network De-anonymization
C. F Chiasserini, M. Garetto, E. Leonardi
Recently, graph matching algorithms have been successfully applied to the problem of network de-anonymization, in which nodes (users) participating to more than one social network…
