DAMUT

our colloquium is a Hybrid event!

Our mathematics department organizes the DAMUT Hybrid colloquium from 12:45 to 13:15 in RA 1501/MS-Teams

Organizers: Alexander Skopalik, Christoph Brune, and Matthias Schlottbom

The colloquia will be partially used to give the floor to several freshly appointed staff members, and partially for internationally well-known speakers. The colloquium will last only 30 minutes (25 minutes of presentation and 5 minutes of discussion).

We will do this on Wednesday, as usual during the lunch break. We hope that all of us will be able to make it.

Alexander, Christoph, and Matthias.

Title: An introduction to probabilistic graphical models for multivariate extremes
Abstract:
Multivariate extreme value theory provides a framework for modeling rare events in complex systems, such as floods in river networks, financial crashes, or heatwaves. A central challenge in extremal dependence modeling is to capture the joint structure of extremes using models that remain flexible yet parsimonious, since extreme observations are typically scarce. In this talk, we discuss how probabilistic graphical models address these challenges. We introduce both directed and undirected graphical models for multivariate extremes built from threshold exceedances, and outline methods for structure and parameter learning in high dimensions. Finally, we present a family of extremal graphical models that enables a parametric representationof conditional independence in extremes, leading to particularly tractable and interpretable statistical methodology.
