🚨New Paper!🚨 How do reasoning LLMs handle inferences that have no deterministic answer? We find that they diverge from humans in some significant ways, and fail to reflect human uncertainty… 🧵(1/10)

Our new paper in #PNAS (bit.ly/4fcWfma) presents a surprising finding—when words change meaning, older speakers rapidly adopt the new usage; inter-generational differences are often minor. w/ Michelle Yang, ‪@sivareddyg.bsky.social‬ , @msonderegger.bsky.social‬ and @dallascard.bsky.social‬👇(1/12)

Huge congratulations to Dr. @vernadankers.bsky.social for passing her viva today! 🥳🎓 It's truly been an honour sharing the PhD journey with you. I wasn’t ready for the void your sudden departure left (in the office and in my life!). Your new colleagues are lucky to have you! 🥺🥰

A blizzard is raging through Montreal when your friend says “Looks like Florida out there!” Humans easily interpret irony, while LLMs struggle with it. We propose a 𝘳𝘩𝘦𝘵𝘰𝘳𝘪𝘤𝘢𝘭-𝘴𝘵𝘳𝘢𝘵𝘦𝘨𝘺-𝘢𝘸𝘢𝘳𝘦 probabilistic framework as a solution. Paper: arxiv.org/abs/2506.09301 to appear @ #ACL2025 (Main)

I guess that now that I have 1% of my Twitter followers follow me here 😅, I should announce it here too for those of you no longer checking Twitter: my nonfiction book, "Lost in Automatic Translation" is coming out this July: lostinautomatictranslation.com. I'm very excited to share it with you!

Presented the AURORA paper together with some of the awesome co-authors Chris Pal @sivareddyg.bsky.social and @ludolara.bsky.social from @Mila_Quebec Tons of fun, 3h of non-stop chatting and exchange of ideas, now pretty exhausted 😅
