Networks in cognitive science
Baronchelli, Andrea; Ferrer Cancho, Ramon; Pastor Satorras, Romualdo; Chatter, Nick; Christiansen, Morten H. (Elsevier, 2013-07-01)
Article
Accés obertNetworks of interconnected nodes have long played a key role in Cognitive Science, from artificial neural networks to spreading activation models of semantic memory. Recently, however, a new Network Science has been ... -
Ordering dynamics of the multi-state voter model
Starnini, Michele; Baronchelli, Andrea; Pastor Satorras, Romualdo (Institute of Physics (IOP), 2012-10-30)
Article
Accés obertThe voter model is a paradigm of ordering dynamics. At each time step, a random node is selected and copies the state of one of its neighbors. Traditionally, this state has been considered as a binary variable. Here, we ... -
Random walks and search in time-varying networks
Perra, N.; Baronchelli, Andrea; Mocanu, D.; Gonçalves, B.; Pastor Satorras, Romualdo; Vespignani, Alessandro (2012-12-04)
Article
Accés obertThe random walk process underlies the description of a large number of real-world phenomena. Here we provide the study of random walk processes in time-varying networks in the regime of time-scale mixing, i.e., when the ... -
Random walks on complex trees
Baronchelli, Andrea; Catanzaro, Michele; Pastor Satorras, Romualdo (2008-07-18)
Article
Accés obertWe study the properties of random walks on complex trees. We observe that the absence of loops is reflected in physical observables showing large differences with respect to their looped counterparts. First, both the vertex ... -
Random walks on temporal networks
Starnini, Michele; Baronchelli, Andrea; Barrat, Alain; Pastor Satorras, Romualdo (2012)
Article
Accés obertMany natural and artificial networks evolve in time. Nodes and connections appear and disappear at various time scales, and their dynamics has profound consequences for any processes in which they are involved. The first ... -
Role of feedback and broadcasting in the naming game
Baronchelli, Andrea (2011)
Article
Accés obertThe naming game (NG) describes the agreement dynamics of a population of agents that interact locally in a pairwise fashion, and in recent years statistical physics tools and techniques have greatly contributed to shed ... -
Scale-free networks emerging from multifractal time series
Budroni, Marcello A.; Baronchelli, Andrea; Pastor Satorras, Romualdo (American Chemical Society (ACS), 2017-05-16)
Article
Accés obertMethods connecting dynamical systems and graph theory have attracted increasing interest in the past few years, with applications ranging from a detailed comparison of different kinds of dynamics to the characterization ... -
The biological origin of linguistic diversity
Baronchelli, Andrea; Chater, N.; Pastor Satorras, Romualdo; Christiansen, M.H. (2012-10-30)
Article
Accés obertIn contrast with animal communication systems, diversity is characteristic of almost every aspect of human language. Languages variously employ tones, clicks, or manual signs to signal differences in meaning; some languages ... -
Voter models on weighted networks
Baronchelli, Andrea; Castellano, Claudio; Pastor Satorras, Romualdo (2011-06-29)
Article
Accés obertWe study the dynamics of the voter and Moran processes running on top of complex network substrates where each edge has a weight depending on the degree of the nodes it connects. For each elementary dynamical step the first ...
