Amortized ProbML: Unlocking Probabilistic Machine Learning for Real-world Inference & Design (🇩🇰) ELLIS UnConference Workshop Copenhagen | 2 December, 2025

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...)

Congrats Marvin! 🎊

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!

Principal Investigator positions at ELLIS Institute Finland | ELLIS Institute Finland Now recruiting new PIs in artificial intelligence and machine learning

If you want to start your own research group in AI & machine learning, with access to top resources for research incl. @lumi-supercomputer.eu, generous starting package & professorship affiliation with a university in the world’s happiest country, apply by March 9: www.ellisinstitute.fi/PI-recruit

Reminder about postdoc and doctoral positions with option to select me as the supervisor for Bayesian topics. The call closes February 2nd. See also many other topics in ML and AI in Finland

Helsinki Probabilistic Machine Learning Lab

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!

1/📯I am hiring! Postdoc position in Probabilistic Machine Learning and Amortized Inference.

@univhelsinkics.bsky.social with strong links to the Finnish Center for AI (FCAI)

Please see blurb and link in thread below.

Applications evaluated on a rolling basis. Please reshare!

Some thoughts on the role of Bayesianism in the age of Modern AI It works because it works.

It’s hot takes Friday 😅

Absolutely excellent post!!

It would be great if you could share some tips in the creation process (like the great drawings) which could inspire more pleasuring posts! 😀

Would love to join if that’s ok. I work on Bayesian inference and ML
