Triggered urn models for frequently asked questions (FAQ)
Irene Crimaldi, Andrea Ghiglietti, Leen Hatem +1
We investigate a nonclassic urn model with triggers that increase the number of colors. The scheme has emerged as a model for web services that set up frequently asked questions (F…
Networks of reinforced stochastic processes: probability of asymptotic polarization and related general results
Giacomo Aletti, Irene Crimaldi, Andrea Ghiglietti
In a network of reinforced stochastic processes, for certain values of the parameters, all the agents' inclinations synchronize and converge almost surely toward a certain random v…
Networks of reinforced stochastic processes: a complete description of the first-order asymptotics
Giacomo Aletti, Irene Crimaldi, Andrea Ghiglietti
We consider a finite collection of reinforced stochastic processes with a general network-based interaction among them. We provide sufficient and necessary conditions in order to h…
The Rescaled Polya Urn and the Wright-Fisher process with mutation
Giacomo Aletti, Irene Crimaldi
In [arXiv:1906.10951 (forthcoming on Advances in Applied Probability),arXiv:2011.05933 (published on PLOS ONE)] the authors introduce, study and apply a new variant of the Eggenber…
Urn models with random multiple drawing and random addition
Irene Crimaldi, Pierre-Yves Louis, Ida Germana Minelli
We consider an urn model with multiple drawing and random time-dependent addition matrix. The model is very general with respect to previous literature: the number of sampled balls…
Interacting non-linear reinforced stochastic processes: synchronization and no-synchronization
Irene Crimaldi, Pierre-Yves Louis, Ida Germana Minelli
'Rich get richer' rule comforts previously often chosen actions. What is happening to the evolution of individual inclinations to choose an action when agents do interact ? Interac…
