Maximum likelihood estimation for social network dynamics [PDF]
, 2009 A model for network panel data is discussed, based on the assumption that the observed data are discrete observations of a continuous-time Markov process on the space of all directed graphs on a given node set, in which changes in tie variables are ...

Visualization methods for longitudinal social networks and stochastic actor-oriented modeling [PDF]
Social Networks, 2012 Abstract As a consequence of the rising interest in longitudinal social networks and their analysis, there is also an increasing demand for tools to visualize them. We argue that similar adaptations of state-of-the-art graph-drawing methods can be used to visualize both, longitudinal networks and predictions of stochastic actor-oriented models (SAOMs),

Modelling and analyzing adaptive self-assembling strategies with Maude [PDF]
, 2015 Building adaptive systems with predictable emergent behavior is a challenging task and it is becoming a critical need. The research community has accepted the challenge by introducing approaches of various nature: from software architectures, to ...

Prevention Science, 2021 Adolescent drinking remains a prominent public health and socioeconomic issue in the USA with costly consequences. While numerous drinking intervention programs have been developed, there is little guidance whether certain strategies of participant recruitment are more effective than others.

End-to-end optimization of goal-driven and visually grounded dialogue systems [PDF]
, 2017 End-to-end design of dialogue systems has recently become a popular research topic thanks to powerful tools such as encoder-decoder architectures for sequence-to-sequence learning.

Stochastic actor oriented model with random effects
Social NetworksThe 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 using both exogenous covariates and endogenous network configurations, but also the co-evolution of behaviour and social interactions.

Friendship Between Banks: An Application of an Actor-Oriented Model of Network Formation on Interbank Credit Relations [PDF]
, 2014 This paper investigates the driving forces behind banks' link formation in the interbank market by applying the stochastic actor oriented model (SAOM) developed in sociology. Our data consists of quarterly networks constructed from the transactions on an

Some Birds Have Mixed Feathers: Bringing the Multiracial Population into the Study of Race Homophily
Sociological ScienceResearch on race homophily in the United States has yet to meaningfully include the growing multiracial population. The present study confronts this challenge by drawing upon recent conceptualizations of race as a multidimensional construct.
