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…
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…
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…
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…
