There are some collaborations that are just fun and this was one of them! Big thank you to Anna Meier and Alessandra Moretti and everyone else involved!🫀

A new method from Johannes Wirth [email protected] Celia P. Martinez-Jimenez Meier Lab - MiBioEng @ HPC enables cost effective spatial transcriptomics on multiple tissues in parallel. PioneerCampus @HelmholtzMunich

📺New video: Curvature for Graph Learning📺 Presenting, among other things, current work with (i) Josh Southern, Jeremy Wayland, Michael Bronstein and (ii) Corinna Coupette and Sebastian Dalleiger. Very excited about this research direction! youtube.com/watch?v=-V0Jpd…


Happy to announce our new paper on Deterministic Uncertainty Methods TrustML-(Un)Limited #ICLR2023 ! We dissect how the design of training schemes, architecture, and prior can significantly impact feature collapse and uncertainty performance! w/ C. Zhang and Stephan Günnemann


1/9 CPAis finally published. It can predict single-cell responses to combinatorial perturbation (drugs, CRISPR). This is a joint collab between @meta and Fabian Theis Helmholtz Munich | @HelmholtzMunich. Read the thread to understand the LEGO analogy! embopress.org/doi/full/10.15…

If you are interested in ML potentials and/or uncertainty estimation come and visit our presentation of "Uncertainty Estimation for Molecules: Desiderata and Methods" this week at #ICML! Tue, 11am, #415 Joint work with Nicholas Gao Bertrand Charpentier Amine Ketata Stephan Günnemann 1/2



Is binarization of scATAC-seq data really necessary? The conclusion from our analysis is that a quantitative treatment is in fact beneficial. Now out in Nature Methods! gagneurlab Fabian Theis nature.com/articles/s4159… Many additions since the preprint 👇(1/n)


Thrilled to present our paper "(Provable) Adversarial Robustness for Group Equivariant Tasks" at #NeurIPS2023! Joint work with great collaborators @YanScholten Stephan Günnemann! Paper: arxiv.org/abs/2312.02708 Poster #800 Thursday 11 am - 13 pm #NeurIPS

Get to know #mcml junior member Leon Hetzel 💡 He developed an algorithm called chemCPA designed to make drug discovery more effective. Read more (in German): mcml.ai/news/2024-03-2… This article was written by Leonie Fischer from Deutsche Journalistenschule!


Mixed Models with Multiple Instance Learning (MixMIL) received an Oral & Outstanding Student Paper award at AISTATS Conference last week! 🏆 MixMIL enables accurate & interpretable patient label prediction from single-cell data by adding attention to GLMMs.#singlecell #MachineLearning


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
