How can we consistently make LLM-generated distributions better align with the opinions of diverse population groups, and evaluate them robustly?
We study this in our paper, “Improving the Distributional Alignment of LLMs using Supervision”, to be presented at #ACL2026! 🧵

Are state-of-the-art AI review systems capable of providing meaningful reviews in an actual AI conference? This paper explains the findings from the AAAI 2026 AI Review Pilot 1/N
We are thrilled to present a detailed report describing the system built for the AAAI-26 AI review pilot, the survey results, and a new benchmark that was created to assess the capabilities of the system.
