Bayesian Poisson Regression and Tensor Train Decomposition Model for Learning Mortality Pattern Changes during COVID-19 Pandemic
Wei Zhang, Antonietta Mira, Ernst C. Wit
COVID-19 has led to excess deaths around the world, however it remains unclear how the mortality of other causes of death has changed during the pandemic. Aiming at understanding t…
Relational Event Modeling
Federica Bianchi, Edoardo Filippi-Mazzola, Alessandro Lomi +1
Advances in information technology have increased the availability of time-stamped relational data such as those produced by email exchanges or interaction through social media. Wh…
Worst-risk minimization in generalized structural equation models
Philip Kennerberg, Ernst C. Wit
We consider rather general structural equation models (SEMs) between a target and its covariates in several shifted environments. Given shifts we consider the set…
A Stochastic Gradient Relational Event Additive Model for modelling US patent citations from 1976 until 2022
Edoardo Filippi-Mazzola, Ernst C. Wit
Until 2022, the US patent citation network contained almost 10 million patents and over 100 million citations. To overcome limitations in analyzing such complex networks, we propos…
Stochastic Actor Oriented Model with Random Effects
Giacomo Ceoldo, Tom A. B. Snijders, Ernst C. Wit
The stochastic actor oriented model (SAOM) is a method for modelling social interactions and social behaviour over time. It can be used to model drivers of dynamic interactions usi…
Analysing ecological dynamics with relational event models: the case of biological invasions
Rūta Juozaitienė, Hanno Seebens, Guillaume Latombe +2
Aim: Spatio-temporal processes play a key role in ecology, from genes to large-scale macroecological and biogeographical processes. Existing methods studying such spatio-temporally…
Drivers of the decrease of patent similarities from 1976 to 2021
Edoardo Filippi-Mazzola, Federica Bianchi, Ernst C. Wit
The citation network of patents citing prior art arises from the legal obligation of patent applicants to properly disclose their invention. One way to study the relationship betwe…
Dynamic latent space relational event model
Igor Artico, Ernst C. Wit
Dynamic relational processes, such as e-mail exchanges, bank loans and scientific citations, are important examples of dynamic networks, in which the relational events consistute t…
A predictive model for planning emergency events rescue during COVID-19 in Lombardy, Italy
Angela Andreella, Antonietta Mira, Spyros Balafas +5
Italy, particularly the Lombardy region, was among the first countries outside of Asia to report cases of COVID-19. The emergency medical service called Regional Emergency Agency (…
