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…

Do you care about uncertainty quantification? Do you like guarantees? Check out our #ICML2023 paper where we bring conformal prediction to Graph Neural Networks. tldr: Instead of a single label return a *set* that is guaranteed to contain the true label. Set size = uncertainty.

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)

It’s rainy in Vancouver, poster hall is closed but we are ready 🙌 👉 Come and talk to us and learn about UniGuide at Poster#2600 (East) UniGuide is a new framework for molecular diffusion models that enables flexible geometric conditioning across tasks—no retraining required
