me: now I've read the basic lit on approximate bayesian computation via bayesflow and I can start trying to distil it on time for the last lecture, to awe the students. @chengkunli.bsky.social : hold my mcmc (really really cool!)

😀 Enter the amortized Bayesian workflow from here 👉 pipme.github.io/amortized-Ba... Huge thanks to my great collaborators: @avehtari.bsky.social, @paulbuerkner.com, @stefanradev.bsky.social, @lacerbi.bsky.social, @marvin-schmitt.com!

All approximations are wrong, but some are useful --> Stacking can make them more useful 😄

Do you like to train neural networks to solve all your nasty probabilistic inference and sequential design problems? Do you love letter salads such as NPs, PFNs, NPE, SBI, BED? Then no place is better than the Amortized ProbML workshop we are organizing at #ELLIS UnConference.

I’ll be at the AABI symposium tomorrow. Looking forward to seeing everyone there!

1/ If you are at ICLR / AABI / AISTATS, check out work from our lab and collaborators on *inference everywhere anytime all at once*! Go talk to my incredible PhD students @huangdaolang.bsky.social & @chengkunli.bsky.social + amazing collaborator Severi Rissanen. @univhelsinkics.bsky.social FCAI

1/ Just saw this paper using our PyVBMC (acerbilab.github.io/pyvbmc/) in structural engineering. Nice to see sample-efficient Bayesian inference for expensive computational models used in the wild! (Although we feel a bit more pressure to triple-check that our implementation has no bugs...)

Multi-Head Latent Attention vs Group Query Attention: We break down why MLA is a more expressive memory compression technique AND why naive implementations can backfire. Check it out!

1/ Introducing ACE (Amortized Conditioning Engine)! Our new AISTATS 2025 paper presents a transformer framework that unifies tasks from image completion to BayesOpt & simulator-based inference under *one* probabilistic conditioning approach. It's Bayes all the way down!

1/ 🎉 We launched the *Helsinki Probabilistic Machine Learning Lab*, which combines multiple research groups at @univhelsinkics.bsky.social - and part of FCAI and ELLIS - working on, guess what, Probabilistic ML and AI. And we are hiring! Please repost! Website: www.helsinki.fi/probabilisti...
