On the perimeter estimation of pixelated excursion sets of 2D anisotropic random fields
Ryan Cotsakis, Elena Di Bernardino, Thomas Opitz
We are interested in creating statistical methods to provide informative summaries of random fields through the geometry of their excursion sets. To this end, we introduce an estim…

High-dimensional variable clustering based on maxima of a weakly dependent random process
Alexis Boulin, Elena Di Bernardino, Thomas Laloë +1
We propose a new class of models for variable clustering called Asymptotic Independent block (AI-block) models, which defines population-level clusters based on the independence of…
