Check out our latest work "Uncertainty for Active Learning on Graphs" at ICML Conference 2024: We prove that epistemic Uncertainty Sampling is an optimal strategy and propose an effective approximate algorithm! Joint work w/ Tom Wollschläger Antonio Oroz Bertrand Charpentier Stephan Günnemann

Presenting at #ICML2024: Fragment-Biases for Molecular GNNs 🧪 Tue, 23.07: Oral session 1F @ 11:00 Poster #105 @ 11:30 🔑 Fragment-Biased GNNs outperform others, match Transformers with better generalization & linear cost! 🤝 With N. Kemper, Leon Hetzel , Johanna Sommer , Stephan Günnemann

Excited to share that my master's thesis on "molecular graph generation in latent Euclidean space" was accepted at Gram Workshop and selected for an oral presentation. If you are at ICML Conference on Saturday, make sure to stop by.


Very happy that our work received the Best Paper Runner-up Award at the GRaM Workshop at ICML 2024! Huge thanks to the organizers, especially Sharvaree Vadgama, for organizing this amazing workshop. And congrats to all my co-authors Nicholas Gao, Johanna Sommer, Tom Wollschläger, Stephan Günnemann. #ICML2024



Pour notre 50ème meetup WiMLDS Paris, nous voyons les choses en grand et accueillons Isabelle Collet et Irène Waldspurger, médaille de bronze #CNRS 2020, chargée de recherche CNRS 🌍 au CEREMADE. Vous venez? C'est Pruna AI qui nous reçoit! #WiMLDSParis meetup.com/paris-women-in…



This week, we will present our recent #NeurIPS2024 paper. 📎 Paper: openreview.net/forum?id=HeoRs… 📆 Make sure to visit our poster #2600 on Fri, 13 December at 11 am! Joint work with my amazing mentors Leon Hetzel Johanna Sommer Fabian Theis Stephan Günnemann




Safe and reliable machine learning has never been more relevant. However, at the same time, LLMs made robustness research **more complex, less reproducible, and harder-to-evaluate**. How can we enable research progress despite these challenges?🧵 Stephan Günnemann Gauthier Gidel


Do you think your LLM is robust?⚠️With current adversarial attacks it is hard to find out since they optimize the wrong thing! We fix this with our adaptive, semantic, and distributional objective. By Stephan Günnemann's lab & Google AI, w/ Center for AI Safety support Here's how we did it. 🧵



Recent HiDream models from vivago.ai (HiDream) rank #1 for image generation? We make them x1.3 to x2.5 faster! 🚀 Directly enjoy the speed on the @Replicate endpoints: • HiDream fast: replicate.com/prunaai/hidrea… • HiDream dev: replicate.com/prunaai/hidrea… • HiDream full:

Happy to share that our paper "Lift Your Molecules: Molecular Graph Generation in Latent Euclidean Space" got accepted to #ICLR2025, and we will be presenting it this week in Singapore! Joint work with Nicholas Gao, Tom Wollschläger, Johanna Sommer, and Stephan Günnemann. 🧵 1/

Thrilled to announce that we just presented „MAGNet: Motif-Agnostic Generation of Molecules from Scaffolds“ at #ICLR2025 🧲 Johanna Sommer Bastian Grossenbacher-Rieck Fabian Theis Stephan Günnemann For those who couldn’t make it to our spotlight: openreview.net/forum?id=5FXKg…


Open-weights Black Forest Labs FLUX.1 Kontext [dev] is now open-source! It allows to perform image-to-image generation with state-of-the-art quality :) However, it takes ~14.4 seconds for each generation on one H100. When we learned about this, we were in our offsite to chill together
