👥 Frustrated by chatbots remembering what you said, but never use the memory correctly? We evaluated 15 SoTA LLM chatbots' ability to apply the memory about a user in downstream tasks. Introducing: 𝑷𝒆𝒓𝒔𝒐𝒏𝒂𝑴𝒆𝒎 Benchmark 🥇Gemini 1.5, GPT4.5, GPT4.1 are in the lead ⬇️

Check out the great recent PhD grad and uber HCI hacker ⁦Jackie Yang⁩ on the last cool piece of his LLM-powered multimodal dev tool! See at #chi2025 at 4:20 in G304! dl.acm.org/doi/10.1145/37… programs.sigchi.org/chi/2025/progr…

1/ 🧵 How does #DifferentialPrivacy affect #hallucinations in LLMs? We find that while DP-SGD *reduces* some hallucinations, it introduces new types of linguistic errors. Join Ivoline Ngong’s oral 2 PM Ballroom B TODAY @NAACL to learn how our method, DPRefine, addresses these

Great job, Anna and Eric! Anna presented our work demonstrating the inconsistency of LLM responses and how attackers might take advantage (doi.org/10.1145/370659…); and Eric investigating health-related tracking and deceptive ads (doi.org/10.1145/370659…) Matthew McCoy

Will AI agents be controlled by big tech companies? Or could they be controlled by users, safeguarding user autonomy and privacy? In a new position paper (accepted to ICML 2025), we outline the steps we need to take now to enable user-centric agents (w/Seth Lazar, Noam Kolt)🧶

We finally answer “do real membership inference attacks really work on lllms?” Super fun collaboration that started out as a conversation in Neurips!

I think the pressing question is: is our peer review system ready to handle a potential wave of agent-generated papers? right now I don’t think it is (yet)
