🚨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 findingβ€”when words change meaning, older speakers rapidly adopt the new usage; inter-generational differences are often minor.

A blizzard is raging through Montreal when your friend says β€œLooks like Florida out there!” Humans easily interpret irony, while LLMs struggle with it. We propose a 𝘳𝘩𝘦𝘡𝘰𝘳π˜ͺ𝘀𝘒𝘭-𝘴𝘡𝘳𝘒𝘡𝘦𝘨𝘺-𝘒𝘸𝘒𝘳𝘦 probabilistic framework as a solution.

Exploiting Instruction-Following Retrievers for Malicious Information Retrieval Parishad BehnamGhader, Nicholas Meade, Siva Reddy

Instruction-following retrievers can efficiently and accurately search for harmful and sensitive information on the internet! πŸŒπŸ’£

Retrievers need to be aligned too! 🚨🚨🚨
