Thea Klaeboe Aarrestad

Particle physicist at @ETH. Like ML, FPGAs and quantum fields. Preferably together. Also at @CERN @CMSexperiment

[Thea Klaeboe Aarrestad @Thea_kaa]

Our review paper on anomaly detection in particle physics is published in Reviews in Physics! Had fun trying to summarize the many moving pieces of a swiftly moving field, with the excellent @ETH_physics PhD students Patrick Odagiu and Vasilis Belis!

When we did our first CMS anomaly detection search we had to come up with a way to calibrate the ML identification of 'exotic' jets we have never seen in data

I developed this new method, now being used by multiple analyses in CMS!

Before physics kept me in academia, now it's students 🥹❤️ @ETH_physics

[A3D3 Institute @a3d3institute]

Exciting news from #NeurIPS2024! 🎉 A3D3 members showcased groundbreaking work in AI for scientific discovery. Check out Dr. Eli Chien's brilliant recap of their talks and posters.

Great talk on real time #ML for physics at the #LHC from @a3d3institute Affiliate Senior Research Fellow (ETH Zurich) today at #NeurIPS2024.

[Thea Klaeboe Aarrestad @Thea_kaa]

Super nice final day at #neurIPS2024 at the Machine Learning and the Physical Sciences workshop #ML4PS2024! Intimidating stage, friendly audience

[Kyle Cranmer @KyleCranmer]

40,000 exabytes per year!
Thea Klaeboe Aarrestad (@Thea_kaa ) talks about the need for nanosecond inference at the Large Hadron Collider. (That’s the raw data rate, we can’t keep it all) #ML4PS2024

[Thea Klaeboe Aarrestad @Thea_kaa]

Such a pleasure, a wonderful event!

[WiML @WiMLworkshop]

We have the amazing @Thea_kaa from @CERN speaking about “Pushing the limits of real-time ML: Nanosecond Inference for Particle Discovery at the LHC”. Join us in room 211 at the Vancouver Convention Center.

[Thea Klaeboe Aarrestad @Thea_kaa]

Excited to join @WiMLworkshop at neurIPS 2024 next week!

[WiML @WiMLworkshop]

Excited to welcome @Thea_kaa, particle physicist at @ETH, a pioneer in #machinelearning for physics, as both speaker and panelist at #WiML at #NeurIPS!

[A3D3 Institute @a3d3institute]

Join us for the #A3D3 seminar on Monday, 11/18 at 12pm PST, "Hunting the Unexpected: Anomaly Detection and Real-Time Triggers at the Large Hadron Collider" by
@Fermilab Wilson Fellow Jennifer Ngadiuba https://t.co/oVDVb8PnWt

[Kyle Cranmer @KyleCranmer]

This seems like as good of a time as any to remind everyone that we have an awesome workshop series at @NeurIPSConf on Machine Learning and the Physical Sciences. That includes both Physics for ML and ML for Physics. #NobelPrize2024 Hinton & Hopfield

@GregorKasieczka @unihh Big congratulations and well deserved <3

[Thea Klaeboe Aarrestad @Thea_kaa]

9.9!

[CMS Experiment CERN @CMSExperiment]

⌛Just released: CMS delivers unprecedented precision in a measurement of the W boson mass at the LHC - and it agrees with the Standard Model! Almost a decade in the making, this result sets a new milestone for precision measurements at hadron colliders: https://t.co/aooujPYV0m

[Thea Klaeboe Aarrestad @Thea_kaa]

Finishing our Foundations of Experimental Particle Physics class early today in order to show the students some Foundations of Experimental Particle Physics. Congratulations @CMSExperiment !

[Thea Klaeboe Aarrestad @Thea_kaa]

Happy anniversary @CERN !

[Thea Klaeboe Aarrestad @Thea_kaa]

From Statistics meets ML in London, to Sustainability meets ML in Belfast! Super excited to learn about emerging technologies for a sustainable future and to discuss how we approach efficient inference at CERN!

[Gregor Kasieczka @GregorKasieczka]

Next up at #PHYSTAT is a key topic where physics applications need to push the boundaries of statistics & ML: anomaly detection.

Great 4-pack of talks by @lilyhzhang @GrossoGaia @Thea_kaa & AndreS

[Machine Learning: Science and Technology @MLSTjournal]

Great new work by @quezq @jmgduarte @GregorKasieczka @Thea_kaa et al @quunihh @ImperialPhysics @ETH_physics @UCSDPhysics @CERN @CMSexperiment - 'Ultrafast jet classification at the HL-LHC' - https://t.co/gWeTpH8EVU #machinelearning #HEP #particlephysics #LHC #jets #FGPA @hls4ml

[Norway in Geneva 🇳🇴 @NorwayInGeneva]

🆕 exhibition in #Geneva⤵️

“Not a Woman’s Job” you said?

The annual @UNGeneva exhibition proves otherwise! Come by the 2024 edition & see those who’ve paved the way, this time science & tech!

Norway is proudly represented by CERN particle physicist Dr Thea Klæboe Årrestad 🇳🇴🙌

[Clemens Lange @clelange]

We have an opening for not only one but two PhD student positions in the High Energy Physics group @psich_en to work on #HiggsBoson physics and related topics with the @CMSExperiment. For more information, see https://t.co/dPjSbGNwcr #HepJobs
