Geometry, Algebra and Physics in Deep Neural Networks

We have an open PhD position with Jan Gerken about symmetries in neural networks.

We seek a PhD student for a project at the intersection of mathematics and deep learning to work on theoretical aspects of geometric deep learning. The question whether more data and compute are sufficient to improve neural networks is highly debated at the moment in all areas of deep learning. In this project, you will work on a theoretical framework which will help to better understand these questions in the context of geometric deep learning and add rigorous arguments to a debate driven by empirical results.

Application Deadline is 21 May 2025.

Our work on Learning Chern Numbers of Topological Insulators with Gauge Equivariant Neural Networks is now on the arXiv! In this paper, we combine lattice gauge equivariant networks with a novel training mechanism to learn topological invariants (Chern numbers) of topological insulators. This paper combines several beautiful topics in machine learning, physics and mathematics.

First author is our master’s student Longde Huang. Congratualtions to his first publication! From our group, Hampus Linander, Daniel Persson and Jan Gerken were also involved. Thanks to our phyiscs-collaborators Oleksandr Balabanov (then at Stockholm University) and Mats Granath (University of Gothenburg) for their expertise and a fun collaboration!

Elias Nyholm is one of the organisers of the LoG Meetup Sweden in Uppsala this year. This two-day workshop is the official local meetup of the online LoG Conference and will consist of keynote talks, contributed talks and a poster session.

The group had a strong presence at the WASP Winter Conference in Norrköping this year, including poster presentations by Elias, Philipp and Oscar.
