EPIGRAPHY had its kickoff event in Lisbon last week, from Feb 12-15, 2026! Lots of interesting talks on #deeplearning, #EdgeAI, and #particlephysics. We also connected with other communities like #EuCAIF, #NextGenTriggers, and @MLQC4FC ! See you soon at the next EPIGRAPHY event!

[EPIGRAPHY @COST_EPIGRAPHY]

We are extremely delighted to announce the kickoff school for our COST Action EPIGRAPHY in Lisbon, from Jan 12-15. While in-person invitations have gone out to EPIGRAPHY members, a public Zoom link will be provided to follow the talks & tutorials online: https://t.co/N4WsTETBTo

[Anthropic @AnthropicAI]

New Anthropic research: Persona vectors.

Language models sometimes go haywire and slip into weird and unsettling personas. Why? In a new paper, we find “persona vectors"—neural activity patterns controlling traits like evil, sycophancy, or hallucination.

🚨 Our paper "Mixture of Expert Graph Transformer for Particle Collision Detection" is now published in Scientific Reports!
🔍 We propose a novel graph-based approach to improve particle collision detection. https://t.co/ySTENXEeFW

[ATLAS Experiment @ATLASexperiment]

🚀 And we're off! On 5 May 2025, the ATLAS Experiment recorded its first 13.6 TeV collisions of the year.

These event displays capture the first moments of a promising new data-taking season at @CERN's flagship particle accelerator. Learn more: https://t.co/pGADLaE3IL

📣 We have beam in the tunnel 💫

Today, the Large Hadron Collider received the first particle beams of 2025. #BeamTime

Protons were injected into the #LHC for the first time since November 2024, when the annual year-end technical stop (YETS) started. This is the fourth year of #LHCRun3, and the new data-taking season is about to begin.

Stay tuned for more #ParticlePhysics news.

*MoE Graph Transformers for Interpretable Particle Collision Detection*
by @d_genovese @devoto_alessio @StefanoG

We propose a MoE graph transformer for particle collision analysis, with many nice interpretability insights (e.g., expert specialization).

BREAKING NEWS
The Royal Swedish Academy of Sciences has decided to award the 2024 #NobelPrize in Physics to John J. Hopfield and Geoffrey E. Hinton “for foundational discoveries and inventions that enable machine learning with artificial neural networks.”

[David Rousseau @dhpmrou]

10 years ago #OTD, @bingxu_ and @tqchenml quietly announced the birth of @XGBoostProject on the @kaggle #higgsml competition forum.
Since then, XGBoost has skyrocketed in popularity to become the top ML go-to tool!

*Kolmogorov-Arnold Networks (KANs)* by @ZimingLiu11 et al.

Since everyone is talking about KANs, I wrote some notes on Notion with a few research questions I find interesting.

First time I do something like this, give me some feedback. 🙃
