High-dimensional networks and mean squared error for possibly misspecified models

Lourens Waldorp

To avoid missing important variables and their connections in networks, more and more variables are included in network analysis. Here we show that in a setting with many more para…

Mean-field theory of the general-spin Ising model

Lourens Waldorp, Tuan Pham, Han L. J. van der Maas

Motivated by modelling in physics and other disciplines, such as sociology and psychology, we derive the mean field of the general-spin Ising model from the variational principle o…

Polarisation in increasingly connected societies

Tuan Pham, Sidney Redner, Lourens Waldorp +2

Explanations of polarization often rely on one of the three mechanisms: homophily, bounded confidence, and community-based interactions. Models based on these mechanisms consider t…

The Principle of Redundant Reflection

Martin Metodiev, Maarten Marsman, Lourens Waldorp +2

The fact that redundant information does not update a rational belief implies that rational beliefs are updated using Bayes rule. In the framework of Hild (1998a), this is true und…

Explaining Clustering of Ecological Momentary Assessment Data Through Temporal and Feature Attention

Mandani Ntekouli, Gerasimos Spanakis, Lourens Waldorp +1

In the field of psychopathology, Ecological Momentary Assessment (EMA) studies offer rich individual data on psychopathology-relevant variables (e.g., affect, behavior, etc) in rea…

Exploiting Individual Graph Structures to Enhance Ecological Momentary Assessment (EMA) Forecasting

Mandani Ntekouli, Gerasimos Spanakis, Lourens Waldorp +1

In the evolving field of psychopathology, the accurate assessment and forecasting of data derived from Ecological Momentary Assessment (EMA) is crucial. EMA offers contextually-ric…
