Estimating covariant Lyapunov vectors from data
Christoph Martin, Nahal Sharafi, Sarah Hallerberg
Covariant Lyapunov vectors characterize the directions along which perturbations in dynamical systems grow. They have also been studied as predictors of critical transitions and ex…
A Process for the Evaluation of Node Embedding Methods in the Context of Node Classification
Christoph Martin, Meike Riebeling
Node embedding methods find latent lower-dimensional representations which are used as features in machine learning models. In the last few years, these methods have become extreme…
The impact of partially missing communities~on the reliability of centrality measures
Christoph Martin
Network data is usually not error-free, and the absence of some nodes is a very common type of measurement error. Studies have shown that the reliability of centrality measures is…
Estimating the sensitivity of centrality measures w.r.t. measurement errors
Christoph Martin, Peter Niemeyer
Most network studies rely on an observed network that differs from the underlying network which is obfuscated by measurement errors. It is well known that such errors can have a se…
