Modelling temporal dynamics of suicidal ideation and behaviour across pre- to early adolescence using a Markov framework
Sieun Lee, Ben Cardoen, Marianne Etherson +10
Understanding the dynamics of suicidal ideation and behaviour in youth and the factors associated with transitions from thoughts to behaviours is critical for early identification,…

ROSA: Metric Amplification on Noisy Graphs with Theoretical Guarantees for Amplified Spectral Distances
Ben Cardoen, Fabian Spill
The paper introduces ROSA, a robust order‑aware spectral amplification operator that strengthens graph distance metrics to more reliably detect weak, localized structural changes i…

Spectral Effects Of Heavy-Tailed Vertex Noise In Geometric Graphs
Ben Cardoen, Jeremy Budd, Enrico Amico +2
We characterize which local matrix structures saturate Weyl's eigenvalue perturbation bound for graph Laplacians under geometrically constrained vertex displacements. Geometric gra…
