Scaling Laws in Particle Physics Data! This is a result I've been itching to share and it's finally out. One of the big open questions is how much better AI-based methods at particle colliders can still become. 1/4

As we go into the Thanksgiving holiday, I wanted to express my thanks to my collaborators @johannbrehmer.bsky.social @glouppe.bsky.social, Juan Pavez, @smsharma.bsky.social. Recently, I was awarded the Pritzker Prize for AI in Science for work on SBI. That wouldn't have never happened without them.

I'll be at NeurIPS next week – together with my @cuspai.bsky.social colleagues @jonkhler.argmin.xyz, @hannahopenshaw.bsky.social, Friso de Kruiff, and @wellingmax.bsky.social. If you'd like to chat about ML for material discovery, generative models, or start-ups made in Europe, ping me!

A common question nowadays: Which is better, diffusion or flow matching? 🤔 Our answer: They’re two sides of the same coin. We wrote a blog post to show how diffusion models and Gaussian flow matching are equivalent. That’s great: It means you can use them interchangeably.

sbi - Simulation-based inference @sbi-devs.bsky.social · 27/11/2024
The sbi package is growing into a community project 🌍 To reflect this and the many algorithms, neural nets, and diagnostics that have been added since its initial release, we have written a new software paper 📝 Check it out, and reach out if you want to get involved: arxiv.org/abs/2411.17337

Milestone: our review paper “The Frontier of Simulation-Based Inference” coauthored with @glouppe.bsky.social & @johannbrehmer.bsky.social hit 1000 citations. I’m very excited about the potential for these methods to transform science! www.pnas.org/doi/10.1073/... simulation-based-inference.org
