We’re thrilled to share that our paper “Weisfeiler and Leman Go Gambling: Why Expressive Lottery Tickets Win” by Lorenz Kummer, Samir Moustafa, Anatol Ehrlich, Franka Bause, Nikolaus Suess, Wilfried Gansterer and Nils Kriege has been accpted at the 42nd International Conference on Machine Learning, July 13th-19th 2025, Vancouver, Canada! This work bridges two important areas…

Further raising awareness for the inherent vulnerabilities of Graph Neural Networks (GNNs) to adversarial Bit Flip Attacks (BFAs), Lorenz presented our group’s latest work “On the Relationship Between Robustness and Expressivity of Graph Neural Networks” by Lorenz Kummer, Wilfried Gansterer and Nils Kriege at the 28th International Conference on Artificial Intelligence and Statistics (AISTATS). In…

With “Crossfire: An Elastic Defense Framework for Graph Neural Networks under Bit Flip Attacks” by Lorenz Kummer, Samir Moustafa, Wilfried Gansterer and Nils Kriege, we presented a novel approach to defending Graph Neural Networks (GNNs) from Bit Flip Attacks (BFAs) at the 39th Annual AAAI Conference on Artificial Intelligence. Crossfire combines innovative techniques like saliency-based…

We are glad to announce our paper “On the Relationship Between Robustness and Expressivity of Graph Neural Networks” by Lorenz Kummer, Wilfried Gansterer and Nils Kriege has been accepted at the 28th International Conference on Artificial Intelligence and Statistics (AISTATS) , which will take place from 3rd – May 5th, 2025 in Mai Kaho, Thailand!…

We are excited to announce the acceptance of our recent work “Crossfire: An Elastic Defense Framework for Graph Neural Networks under Bit Flip Attacks” by Lorenz Kummer, Samir Moustafa, Wilfried Gansterer and Nils Kriege at the 39th Annual AAAI Conference on Artificial Intelligence, which will take place in Philadelphia, Pennsylvania, USA from February 25 –…
