Just created the “boomers @ Neurips” group in #neurips Whova app. I had to.

Today ends the #ML4Jets conference in Paris. Great to see the progress in the field from one year to the next, with no saturation in sight. Below some @quunihh students & collaborators (and, of course, beautiful #Paris) Many thanks to AnjaB & @dhpmrou et al for hosting this!

Excited to share the first results using Neural Simulation-Based Inference (NSBI) techniques applied to @ATLASexperiment data! We measure the elusive off-shell Higgs boson with 3.1x better observation sensitivity than standard (histogram) analysis techniques! A thread: (1/N)

I'm happy and proud to present the results of the #CaloChallenge! arxiv.org/abs/2410.21611 A huge thank you to everyone who contributed to this effort in the past year(s)! 1/12

But making it happen in an actual experiment at the LHC took a long time. Check out the thread by @Aishik_Ghosh_ about his 6-year journey. And shoutout to @dhpmrou for being an awesome advisor that saw the potential for these techniques early on xitter.cf/glouppe/status/1851168…
Gilles Louppe@glouppe29 Oct 2024
They made it! @Aishik_Ghosh_, Jay Sandesara, @dhpmrou and Rafael CLdS pushed through the first neural simulation-based inference analysis @ATLASexperiment. Huge congratulations to everyone involved!

A thread on quantum interference and the 6 year adventure it took me through In experimental particle physics we sift out events from signal (eg. Higgs) processes vs the orders of magnitude more events from background processes…

.@brucedenby is the author of the very first paper on AI and Particle Physics back in 1988, when he was a post-doc in Orsay ( @IJCLab @cnrs_in2p3) working in the @CERN LEP DELPHI experiment. He was almost fired for this! #HEPML @dorigo @KyleCranmer @GregorKasieczka

He told us his story in the Learning to Discover workshop I helped organised in April 2022 at @pascalinstitut sponsored by @dataia indico.ijclab.in2p3.fr/event… (search for "Denby" for the talk slides and video )

Learning to Discover

Overall program   The agenda is final. Slides and talk recordings are publicly available from the "Timetable" The event is run in hybrid mode, however, connection details are only made available to...

AI and physics is not a solved problem ! Check out the #NeuriPS 2024 Fair Universe HIggsML Uncertainty challenge to develop AI algorithms measuring the physics properties of elementary particles with imperfect simulators, with controlled uncertainties. fair-universe.lbl.gov

I was today's year old when I realised the Cerenkov light cone was *behind*, not *in front of*, the particle travelling faster than light in the material (from left to right here) . Completely obvious of course. Shame, shame. indico.in2p3.fr/event/33412/…

Looking for a good example of use-inspired research where a physics problem fosters a highly impactful general-purpose method? I’m not talking about MCMC or HMC, I’m talking about @XGBoostProject
