EurIPS Conference @euripsconf.bsky.social · Sep 1

Is your company interested in reaching Europe's leading AI researchers?

If so, don't worry! There are still plenty of opportunity to support #EurIPS as a sponsor. Sponsorship packages are available and can be further customized if necessary.

📣 Please share: We invite submissions to the 29th International Conference on Artificial Intelligence and Statistics (#AISTATS 2026) and welcome paper submissions at the intersection of AI, machine learning, statistics, and related areas. [1/3]

I guess it's great to know about it but, gosh, all the detail... Perhaps variable elimination is a good compromise.

Robert Peharz @ropeharz.bsky.social · Aug 9

I'll weigh in with Bayesian networks: excellent to understand conditional independence, probabilistic structure and information flow.

A curious @neuripsconf.bsky.social experience: review obviously LLM-generated (but with positive score), we report this to the AC. AC tells us to engage nevertheless (?) and is also poking the reviewer. The discussion just becoming more and more obscure...

Let's say the more submissions the truer the statement 😅
About doubts of a proof and these things: yes, that's what I meant with "not substantially worse".

Robert Peharz @ropeharz.bsky.social · Aug 2

Absolutely. We would have #EurIPS now in Copenhagen, but, presentation there is just optional. Each paper must still be presented live in San Diego. This whole @neuripsconf.bsky.social ethical correctness yada yada is merely a fig leaf.

Martin Trapp @trappmartin.bsky.social · Aug 2

The world is a beautiful and fragile place that we are allowed to enjoy temporarily and should feel responsible for.

It’s regrettable that we (the ML community) don’t manage to have decentralised conferences across the globe (look at you, @neuripsconf.bsky.social).

Let's be better together!

Robert Peharz @ropeharz.bsky.social · Aug 2

Hot take (as AC and author): the whole #NeurIPS review process, as is, would not become substantially worse if we just left away the whole rebuttal and discussion phase.

The trick adopted from #probabilistic #circuits: make PCs deep and structured, representing an exponential number of polynomials! DeepPCE nicely scales to thousands of inputs and is competitive with standard deep neural nets. Big bonus: tractable expectations, covariances and Sobol indices!

Robert Peharz @ropeharz.bsky.social · Jul 30

PCE, a classical physical surrogate model, is a linear combination of (tensorproducts of) orthogonal polynomials. But, it doesn't scale gracefully to high dimensions, as the number of polynomials grows exponentially in the number of input dimensions. Also sparseness only helps to a limited extent.

Many thanks for the best paper award for our Deep Polynomial Chaos Expansion (DeepPCE), received from the #UAI workshop #tractable #probabilistic #modeling #TPM! Many congrats to the team, especially leading author Johannes Exenberger!

My maternity leave project is now somewhat out: I made a jupyterbook about the basics of ML, that I teach at TUE. You can check it out here:

The linA part is not yet formulated out and there are other todos, but maybe it helps someone with their own course design 😅

Hey Prof, not sure whether I passed the exam today, since I didn't bother studying for the subject you are teaching (lol). Anyway, I realize now that I'm in trouble and really need a positive grade very soon. Can you do some extra arrangements for your favourite out of 640 students??
