At the two-day workshop, early career scientists gained insights into machine learning and its theoretical concepts in various ways. Following a basic lecture in three parts by Prof. Dr. Bauckhage, all participants had the opportunity to try out what they had learned in practical application exercises. On the second day, lectures provided insights on the application of “Physics-informed Neural Networks” (PINN) to model gene regulation in stem cells (Dr. Maria Mircea), the use of generative AI models for physical questions (Dr. Kim Nicoli) and the Use of “Active Learning” for behavior analysis in neuroscience (Dr. Jens Tillmann). The event ended with a small networking session in which the participants were able to exchange information about their research and what they had learned during these two days of workshop.

We would like to thank the excellent speakers and dedicated tutors for their contribution to the success of this workshop!

October 20, 2023

 3rd workshop of DFG funded research unit FOR 2535 - Anticipating Human Behavior at Hörsaalzentrum Campus Poppelsdorf. Presentations dealt with recent approaches that anticipate human behavior from video or other sensor data. The goal was to bring together researchers from multiple fields and perspectives, and to discuss major research problems and opportunities and how we should coordinate efforts to advance the field.

September 4-5, 2023

This workshop came to live to adress the tremendous progress on large scale machine learning for numerical weather prediction, take stock of developments and discuss possible next steps and open research frontiers. The workshop brought together researchers from industry, modeling centers and academia and provided a forum for detailed discussions on the subject. Scientific organizers were Martin Schultz (Jülich Supercomputing Center), Matthew Chantry (ECWMF), Christian Lessig (ECMWF) and Jürgen Gall (University of Bonn). The event was jointly supported by ECMWF, TRA Modelling and the ERC Advanced Grant IntelliAQ.

June 15, 2023

We invited young researchers for a network opportunity at a special location.

More than 20 participants came together in the exhibition rooms of the "Deutsches Museum Bonn" for two rounds of flash talks plus networking time and fun.

Mission Networking was jointly organized with TRA Matter, TRA Life and Health and BFB. 

April 26, 2023

This transdisciplinary event was organized with TRA Individuals and Societies, HCM, ECONtribute, and TRR EPoS. The aim was to bring together practitioners and developers of methods to discuss the latest advancements and their application in the social sciences.

Talks covered a variety of topics, including quadrature and optimization. Keynote speaker, Ken Judd, with degrees in Computer Science, Math, and Economics, embodied the transdisciplinary spirit that we hoped to foster. 

Program:

• Uta Seidler "High-dimensional quadrature methods and their application in economic models"
• Ole Wilms "Small Data': Efficient Inference with Occasionally Observed States"
• Janos Gabler "Tranquilo: A trust-region optimizer for economists by economists"
• Ken Judd (Keynote) "Dynamic Stochastic Integration of Climate and Economy: An Example of How Third Millennium Computational Science Could Help Social Decisionmaking"

Organizers: Michael Griebel and Hans-Martin von Gaudecker

Lecture series in 2022 (May 23, June 27 and July 20)

Open Source Economics (OSE) is a platform for reproducible research with modern tools. OSE meets Industry was a series of talks in which companies involved in modeling provide insight into their strategies for addressing real-world problems. The talks discussed solved and unsolved problems. Through active interaction between presenters and audience we hoped to bring industry and academia one step closer.

The last talks were:

• OSE meets Comma Soft AG
• OSE meets Deutsche Bank AG
• OSE meets AXA Konzern AG

It was a great pleasure to host the one-day ‘Symposium on Interdisciplinary Research in Mathematics and Life Sciences’, which was held in the Hörsaalzentrum of the University of Bonn and online on Monday, August 30, 2021.
