Hyperevent network modelling of partially observed gossip data
Veronica Poda, Veronica Vinciotti, Ernst C. Wit
Gossiping is a widespread social phenomenon that shapes relationships and information flow in communities. From a network theoretic point of view, gossiping can be seen as a higher…
Causal generalized linear models via Pearson risk invariance
Alice Polinelli, Veronica Vinciotti, Ernst C. Wit
Prediction invariance of causal models under heterogeneous settings has been exploited by a number of recent methods for causal discovery, typically focussing on recovering the cau…
Causal drivers of dynamic networks
Melania Lembo, Ester Riccardi, Veronica Vinciotti +1
Dynamic networks models describe temporal interactions between social actors, and as such have been used to describe financial fraudulent transactions, dispersion of destructive in…
Relational event models with global covariates
Melania Lembo, RÅ«ta JuozaitienÄ, Veronica Vinciotti +1
Bike sharing is an increasingly popular mobility choice as it is a sustainable, healthy and economically viable transportation mode. By interpreting rides between bike stations ove…
Inferring the dynamics of quasi-reaction systems via nonlinear local mean-field approximations
Matteo Framba, Veronica Vinciotti, Ernst C. Wit
In the modelling of stochastic phenomena, such as quasi-reaction systems, parameter estimation of kinetic rates can be challenging, particularly when the time gap between consecuti…
