Modeling Documents with Event Model [PDF]
Algorithms, 2015 Currently deep learning has made great breakthroughs in visual and speech processing, mainly because it draws lessons from the hierarchical mode that brain deals with images and speech. In the field of NLP, a topic model is one of the important ways for modeling documents. Topic models are built on a generative model that clearly does not match the way

Dynamic survival risk prediction with time‐varying high‐dimensional images
Canadian Journal of Statistics, EarlyView.Abstract Integrating longitudinal data with survival models is a prevalent strategy for dynamic survival risk prediction while accounting for subjects' longitudinally observed variables. However, existing methods primarily focus on scalar longitudinal data and seldom tackle the complexities associated with high‐dimensional longitudinal imaging data ...

Copula‐based joint modelling of emergency department visits with time‐varying dependence
Canadian Journal of Statistics, EarlyView.Abstract Jointly modelling multiple correlated count time series is essential in health services research, where outcomes like emergency visits for mental health and substance use often evolve together. Ignoring these dependencies can obscure meaningful trends and limit the effectiveness of policy evaluation.

Brandenburg – Berlin: Modelle künftiger Zusammenarbeit
Raumforschung und Raumordnung, 1993 Brandenburg und Berlin sind durch Nachbarschaft zur Zusammenarbeit verurteilt. Dies gilt besonders für die Regional- und Landesplanung. Solange es nicht zu einer Vereinigung der beiden Länder kommt, sind bei der räumlichen Planung drei Ebenen der ...

Canadian Journal of Statistics, EarlyView.Abstract This article presents a strategy for conducting regression analysis of zero‐truncated recurrent event data. The research is partly motivated by a pediatric mental health care (PMHC) program based on administrative data. We are particularly interested in how the occurrence of an event depends on its past occurrences and the associated ...

Die Konstruktion komplexer historischer Modelle
Österreichische Zeitschrift für Geschichtswissenschaften, 1997 In this article, an exploration of a „second order variety" is undertaken which concludes with some new insights into the long-running debate on the reversibility or irreversibility of historical processes.

Is the Voter Model a Model for Voters? [PDF]
Physical Review Letters, 2014 The voter model has been studied extensively as a paradigmatic opinion dynamics' model. However, its ability for modeling real opinion dynamics has not been addressed. We introduce a noisy voter model (accounting for social influence) with agents' recurrent mobility (as a proxy for social context), where the spatial and population diversity are taken ...

Nonparametric maximum likelihood estimation of the survival function using current lifetime data
Canadian Journal of Statistics, EarlyView.Abstract An issue when estimating the failure time survival function is how to set up a prevalent cohort study infrastructure to follow subjects after enrollment. This problem can be circumvented through the well‐known Grenander density estimator using current lifetime observations only.
