The surprisingly big health benefits of just a little exercise ‘Exercise snacks’ and other forms of everyday movement can greatly reduce the risk of heart disease and death.

A feature in Nature reports how research shows that ‘exercise snacks’ and other forms of everyday movement can greatly reduce the risk of heart disease and death. #medsky 🧪

Is life2vec a mess? What the internet got wrong. Over the past two years, online death calculators have flooded the internet. I think the craze really took off after the introduction of…

It’s been two years since we published the #life2vec paper, and it’s still circulating widely.
People keep discovering it but much of what circulates online is misleading.
Agter a long time, I finally wrote a short explainer to clear up a few things:

Attending @neuripsconf.bsky.social this week!
If you want to chat about LLMs for behaviour / health / labour modeling... or about beliefs and opinions of LLMs, hit me up.

I’ll also be presenting a poster on truth tracking at the Mechanistic Interpretability workshop later. Come say hi!

My 2 cents: If you exploited the #openreview bug or are actively searching for the leaked data, you should seriously reconsider your place in research.
If you cannot uphold the basic principle of double-blind review, how can we trust anything you publish?

Truthfulness isn’t always binary. Sometimes it’s… neither 🤔 Our Trilemma of Truth paper is headed to the @neuripsconf.bsky.social Mechanistic Interpretability workshop 🚀 Let’s connect in San Diego! 🌴

Had the pleasure of presenting our work on Three-valued veracity probes for LLMs at #NEMI Workshop! Mechanistic Interpretability has such a great and welcoming community.
If we crossed paths - let’s connect! 🚀

@nunetsi.bsky.social had a great week at @ic2s2.bsky.social! Looking forward to the next #IC2S2 in Vermont 🔬⛰️

🎥 All keynote talks from IC²S² ‘25 are now available on our YouTube channel!

Colleagues are making sure that I stay focused at #IC2S2 🤓

Presented our work on veracity-tracking in LLMs at #IC2S2 today!
Now looking forward to the next few days of great talks and conversations ✨️🎓

carlomarxx/trilemma-of-truth · Datasets at Hugging Face We’re on a journey to advance and democratize artificial intelligence through open source and open science.

Little wins: our "Trilemma of Truth" dataset just hit 150 downloads. It contains true, false, and neither-valued statements (inspired by the three-valued logic) used to stress-test LLMs for fact-checking, veracity tracking, and uncertainty handling.

Perfect weather, charming streets, and a poster so big it almost needed its own boarding pass 🧳✨
Excited to attend #IC2S2 in Norrköping 🇸🇪 Find me at the Poster Session on Tuesday: "Improving Probes that Track Veracity in Large Language Models" (Poster ID: 39) 🧪

I’m presenting a poster on my latest project: “The Trilemma of Truth.”
Drop by to see how LLMs leverage three‑valued logic to model truth 🔢🤖

Germans Savcisens, Tina Eliassi-Rad: The Trilemma of Truth in Large Language Models https://arxiv.org/abs/2506.23921 https://arxiv.org/pdf/2506.23921 https://arxiv.org/html/2506.23921

The Trilemma of Truth in Large Language Models We often attribute human characteristics to large language models (LLMs) and claim that they "know" certain things. LLMs have an internal probabilistic knowledge that represents information retained d...

🚨 New preprint!
Do LLMs really know what’s true?

In our paper, @eliassi.bsky.social and I introduce sAwMIL: a probing method that distinguishes between true, false, and neither—capturing what LLMs actually “retain.”

We evaluated 16 open models across 3 new datasets.

That happens way too often to me 🥲

Thanks 😋

What's the coolest guide/source on "Complex Data Visualization"? I am looking for some inspiration to visualize graphs and high dimensional data.

Scientists rise up against statistical significance Valentin Amrhein, Sander Greenland, Blake McShane and more than 800 signatories call for an end to hyped claims and the dismissal of possibly crucial effects.

Great read from 2019 about abandoning the use of p-values in a dichotomous way and what we can do instead. More thinking, and less relying on significance tests to decide things for us!

Sometimes we need a reality check 😉 @serge.belongie.com

Amazing time with the folks from @tint-philosophy.bsky.social at the retreat on Predictability of Human Lives. Great people & discussions, and so much to reflect on—especially around integrative modeling and how neural networks can help us get there. Plus, a relaxing sauna to top it off!

Visiting @mpidr.bsky.social this week—super excited to see what’s happening in Demographic Studies (don’t miss my talk!).
Also, I’ll be in Berlin on Feb 2, Helsinki from Feb 3-6, and Copenhagen from Feb 10-12. Let me know if you’re around and up for a coffee 🧪🔬☕️

New tool to estimate the level of participation in collective action expressed in natural language.
Applied to social media, it can produce large-scale and granular estimates of behavior change wrt collective action.

I once asked ChatGPT how it thinks my life would look like in 20 years. And "Visionary Multidimensional Social Scientist" sounds like a great job title 😅 I guess it captured my love for the "His Dark Materials" trilogy.

Happy to write this News & Views piece on the recent audit showing LLMs picking up "us versus them" biases: www.nature.com/articles/s43... (Read-only version: rdcu.be/d5ovo)

Check out the amazing (original) paper here: www.nature.com/articles/s43...

Could you add me as well 🦋🦋

I don't like the way many CS papers are written, even the supposedly good ones, but these tips are very generically applicable and useful. Just ignore the bit about the acronyms...
