This was some work I did Meta FAIR this summer (more on the way!)

We infer general utilities using LLM text-embeddings, assuming participants derive high utility from questions semantically similar to ones they propose (3/7)
LLM-generated questions achieve representation levels comparable to—or better than—the theoretically optimal subsets, and consistently outperform human-selected slates (lower value is better) (5/7)
🚨 New paper! 🔍
“Question the Questions: Auditing Representation in Online Deliberative Processes”
In deliberative polls, participants propose questions for experts but only a few make it to the panel. How representative are those chosen questions of everyone’s interests? 🧵👇
We formalize representation using Justified Representation (JR) from social choice theory and introduce the first efficient algorithms for auditing JR in general utility settings (2/7)
Our auditing tools are integrated into a deliberation platform
used in 50+ countries, allowing moderators to measure and improve representation in real time (thanks, Harshvardhan Agarwal and others!) (6/7)
