1st Graz Mathematical Colloquium

Under the umbrella of NAWI Graz, University of Graz and TU Graz are initiating a new colloquium series in which we bring renowned mathematicians to present an overview of their field in a keynote presentation aimed at a general mathematical audience. We are very happy to announce that the 1st Graz Mathematical Colloquium will take place on Friday, December 13, 2024, at 16:30 in lecture hall 11.02 (Heinrichstraße 36).

This year, the colloquium will also serve as the official kick-off of the NAWI Master Programme Data Science, for which we welcome a representative of the NAWI Steering Committee for an opening statement.

For the mathematical keynote we are very much looking forward to welcome Marcelo Peyrera (Heriot-Watt University, Edinburgh, UK) for a talk titled “A numerical tour of modern Bayesian computational imaging”, an abstract is provided below.

Afterwards, there will be a seasonally appropriate opportunity for informal discussions.

Abstract: In this talk, we first introduce the Bayesian statistical paradigm for performing inference in inverse problems that are ill-conditioned or ill-posed. This is then followed by an introduction to modern high-dimensional Bayesian computation approaches based on numerical approximations of the overdamped Langevin stochastic differential equation. We pay special attention to inference strategies that intimately combine ideas from Bayesian decision theory, stochastic sampling, optimisation, and machine learning. Key concepts and techniques are illustrated through a series of numerical experiments related to computational imaging.
