Assessing the universality of Habitat Suitability Indexes (HSI) for brown trout (Salmo trutta L.) In relation to ecohydraulic variables
Giovanni De Cesare, Paolo Perona, Giulio Calvani, Francesca Padoan
The Habitat Suitability Index (HSI) is a quantitative index that determines the capacity of a given area to meet habitat requirements for a specific species with respect to given variables. The degree of universality of this index is not well understood ye ...
2024An Ordinal Latent Variable Model of Conflict Intensity
Measuring the intensity of events is crucial for monitoring and tracking armed conflict. Advances in automated event extraction have yielded massive data sets of '' who did what to whom '' micro-records that enable datadriven approaches to monitoring confl ...
Assoc Computational Linguistics-Acl2023Networks with correlated edge processes
Sofia Charlotta Olhede, Mária Süveges
This article proposes methods to model non-stationary temporal graph processes motivated by a hospital interaction data set. This corresponds to modelling the observation of edge variables indicating interactions between pairs of nodes exhibiting dependenc ...
OXFORD UNIV PRESS2023From Probability Graphical Models to Dynamic Networks — A Bayesian perspective on Smooth Best Estimate of Trajectory with applications in Geodetic Engineering
Laurent Valentin Jospin, Jesse Ray Murray Lahaye
Bayesian statistics is concerned with the integration of new information obtained through observations with prior knowledge, and accordingly, is often related to information theory (Jospin 2022). Recursive Bayesian estimation methods, such as Kalman Filter ...
2023Comparison of questionnaire items for discomfort glare studies in daylit spaces
Marilyne Andersen, Jan Wienold, Caroline Karmann, Sneha Jain, Geraldine Cai Ting Quek, Clotilde Marie A Pierson
When studying discomfort glare, researchers tend to rely on a single questionnaire item to obtain user evaluations. It is unclear whether the choice of questionnaire item affects the distribution of user responses and leads to inconsistencies between studi ...
2023Non-intrusive data-driven reduced-order modeling for time-dependent parametrized problems
Jan Sickmann Hesthaven, Junming Duan
Reduced-order models are indispensable for multi-query or real-time problems. However, there are still many challenges to constructing efficient ROMs for time-dependent parametrized problems. Using a linear reduced space is inefficient for time-dependent n ...
San Diego2023Using Gaming Footage as a Source of Internet Latency Information
Catalina Paz Alvarez Inostroza
Keeping track of Internet latency is a classic measurement problem. Open measurement platforms like RIPE Atlas are a great solution, but they also face challenges: preventing network overload that may result from uncontrolled active measurements, and maint ...
2023Model-Based Clustering of Trends and Cycles of Nitrate Concentrations in Rivers Across France
Elevated nitrate from human activity causes ecosystem and economic harm globally. The factors that control the spatiotemporal dynamics of riverine nitrate concentration remain difficult to describe and predict. We analyzed nitrate concentration from 4450 s ...
SPRINGER2022Causal modelling of heavy-tailed variables and confounders with application to river flow
Anthony Christopher Davison, Valérie Chavez
Confounding variables are a recurrent challenge for causal discovery and inference. In many situations, complex causal mechanisms only manifest themselves in extreme events, or take simpler forms in the extremes. Stimulated by data on extreme river flows a ...
SPRINGER2022Hiding in Plain Sight: The Issue of Hidden Variables
Here we discuss "hidden variables", which are typically introduced during an experiment as a consequence of the application of two independent variables together to create a stimulus. With increased sophistication in modern chemical biology tools and relat ...
