FAU MoD Lecture: Thoughts on Machine Learning
Speaker: Prof. Dr. Rupert Klein
Affiliation: Mathematik & Informatik, Freie Universität Berlin (Germany)

Abstract. Techniques of machine learning (ML) find a rapidly increasing range of applications touching upon social, economic, and technological aspects of everyday life. They are also being used with great enthusiasm to fill in gaps in our scientific knowledge by data-based modelling approaches. I have followed these developments for a while with interest, concern, and mounting disappointment. When these technologies are employed to take over decisive functionality in safety-critical applications, we would like to exactly know how to guarantee their compliance with pre-defined guardrails and limitations. Moreover, when they are utilized as building blocks in scientific research, it would violate scientific standards -in my opinion- if these building blocks were used without a throrough understanding of their functionality, including inaccuracies, uncertainties, and other pitfalls. In this context, I will juxtapose (a subset of) deep neural network methods with the family of entropy-optimal Sparse Probabilistic Approximation (sSPA) techniques developed recently by Illia Horenko (RPTU Kaiserslautern-Landau) and colleagues.

BIO.- Rupert Klein holds a doctorate degree (1988) and habilitation (1995) in Mechanical Engineering from RWTH Aachen University with specialization in “Nonstationary Mechanics”. Following his rising interest in environmental science, he accepted an offer to take up a professorship on “Safety Technological” at Bergische Universität Wuppertal in 1995. Two years later, he received a two-legged appointed by Freie Universität Berlin (FUB) and the Potsdam-Institut for Climate Impact Research (PIK) to become the head of the “Data & Computation” Department at PIK (1997-2007) and to establish a research group on “Scientific Computing/Modelling and Simulation of Global Environmental Systems” within the Mathematics & Informatics Department of FUB. His research covers topics of theoretical and computational fluid dynamics in a broad sense, with applications to atmospheric flows, vortex dynamics, and combustion.
