- Reposted by Michele CeriottiIf you got curious by the PET-OAM results a week ago, you can learn more reading up arxiv.org/abs/2601.16195. Including some general considerations on how to train and use safely an unconstrained ML potential.
- Reposted by Michele CeriottiWe just kick-started our first workshop of the year, the CECAM Flagship workshop “A Roadmap for an Atomistic Machine Learning Software Ecosystem” - laptops open, ideas humming, and the groove has begun. www.cecam.org/workshop-det...
- Reposted by Michele CeriottiNot going to make a big deal out of a benchmark table, but PET just got the top spot on matbench-discovery.materialsproject.org. And don't be fooled by the huge parameters count, it's faster and can handle larger structures than eSEN-30M 🚀. Kudos to 🧑🚀 Filippo, Arslan and Paolo!

- Reposted by Michele Ceriotti📢 chemiscope.org 1.0.0rc1 just dropped on pypi! We are making (a few) breaking changes to the interfaces, fixing a ton of bugs and introducing some exciting features (you can finally load datasets with > 100k points!). We'd be grateful if you test, break and report 🐛 github.com/lab-cosmo/ch...
- Playing around with humidity sensitive salts with the kiddos. Pink/blue is CoCl2, green/brown is CuCl2, light blue Cu(OH)2. Other ideas? Possibly not too toxic, and possibly that I can make with scrap metals, HCl, H2O2 and ammonia.
- Teachers have been striking two days a week for a month in Vaud. As a parent, it's a pain, but they're right to strike. Cutting public services that work well when there is no budget crisis and no debt is idiotic and self-damaging. Taxes are so effing low in 🇨🇭 anyway!
- BTW same applies to the brilliant foresight of cutting the budget of the @snsf.ch, one of the best-run national science agencies I've ever interacted with, and one that has provided immense return on investment making 🇨🇭 a hub for innovation.

- Reposted by Michele CeriottiNo day goes by without a new universal #ML potential. But how different they really are? Sanggyu and Sofiia tried to give a quantitative answer by comparing the reconstruction errors between their latent-space features.

- San Diego! Must admit I did miss the perpetual summer.
- Another day, another talk. Looking forward to the impromptu workshop organized by Yang Shao-Horn's lab!
- Boston dawn at the #MRS25. One talk done, two to go for this 🇺🇸 pre-xmas grand tour. May the saint protector of jet lag help me.
- Yearly reminder that growing food is hard.
- the ICLR review process is rapidly turning into a theater of the absurd 🍿
- I was very curious of the @iclr-conf.bsky.social experiment of allowing LLM use in reviews, as I've used LLMs to "self-review" @labcosmo.bsky.social manuscripts and found it quite powerful. Sadly, what I'm seeing is all slop. I thought CS grad students would be better at LLMs. Experiment failed 🤷
- Reposted by Michele Ceriotti📢 PET-MAD is here! 📢 It has been for a while for those who read the #arXiv, but now you get it preciously 💸 typeset by @natcomms.nature.com Take home: unconstrained architecture + good train set choices give you fast, accurate and stable universal MLIP that just works™️ www.nature.com/articles/s41...

- Time to reach for the wallet. And maybe time for the PSF to consider relocating to a country that is not sliding into the dark ages, or at least not so quickly.

- Looks like @ox.ac.uk forbids their researchers to do any kind of literature search, though it seems that thankfully they can still submit to the arxiv arxiv.org/abs/2510.00027 🤷

If you are a talented, motivated student, please apply here www.epfl.ch/labs/cqsl/jo.... I am especially looking to hire in scientific ML applications/NQS; not in quantum computing.
- Flying ITA and 🤞 I'll make it alive. Total shitshow. I think they'll end up bankrupt like all the Alitalia descendants have before them, hope after I land.
- Reposted by Michele Ceriotti📝 We have been told (& been telling) that ML potentials are linked quite directly to the expansion of the atomic energy into pairs, triples, and so on.

- 📢 Shout-out for `scwidgets`, a library of ipython widgets to make interactive pedagogic notebooks without all the boilerplate code. I started it for a "computational thinking" class at @materials-epfl.bsky.social. Thanks to many 🧑🚀, led by Alex Goscinski, it's now clean, documented and on pypi.
- With Giovanni Pizzi and the @nccr-marvel.bsky.social and @cecamevents.bsky.social crews, we also wrote a little paper, just landed on the #arXiv, to explain the philosophy and the basic usage arxiv.org/html/2507.05.... Your students deserve better than scroll through 50 lines of matplotlib madness!
- You can `pip install scwidgets` right away, check the documentation here arxiv.org/html/2507.05... and see how I used it for a BSc course here github.com/ceriottm/iam... and for something more advanced here github.com/ceriottm/aml.... Have fun and open issues!
- Very eloquent letter from a bunch of Swiss-based Field medalists science-under-threat.com Switzerland has been extremely generous in funding its researchers, and has reaped huge returns. Cutting because of a completely artificial deficit brake is entirely avoidable self-mutilation.
- Reposted by Michele CeriottiVery proud to send Filippo Bigi to Vancouver to give an oral presentation at @icmlconf.bsky.social about our investigation of the use of "dark-side forces" in atomistic simulations. The final version is here openreview.net/forum?id=OEl... and it's worth a read even if you already read the #preprint

- I rarely have been more excited about one of our papers. Come join the PET-MADness, to get better #ML potentials with less data 📈!
- 📢 PET-MAD has just landed! 📢 What if I told you that you can match & improve the accuracy of other "universal" #machinelearning potentials training on fewer than 100k atomic structures? And be *faster* with an unconstrained architecture that is conservative with tiny symmetry breaking? Sounds like 🧑🚀

- Reposted by Michele CeriottiWhy did pages supporting DEI need to be "under review" in the first place? @asm.org is not a government organization. It is not subject to the Executive Orders, which call for the systematic erasure of many ASM members. This is a pathetic, cowardly excuse for voluntarily complying with fascism.
