A Dataset for Dynamic Human Preferences for Vision Language Models

Hannah Gao, Dylan Hadfield-Menell, Rachel Ma

Given the increased adoption of Vision Language Models (VLMs) in human-interactive settings, it is important that we evaluate how well these models can adapt to real-time preferenc…

Distributional Process Reward Models: Calibrated Prediction of Future Rewards via Conditional Optimal Transport

Rachel Ma, Dylan Hadfield-Menell, Kristjan Greenewald

Inference-time scaling methods rely on Process Reward Models (PRMs), which are often poorly calibrated and overestimate success probabilities. We propose, to our knowledge, the fir…

Flexible Agent Alignment with Goal Inference from Open-Ended Dialog

Rachel Ma, Jingyi Qu, Andreea Bobu +1

We introduce Open-Universe Assistance Games (OU-AGs), a formal framework extending assistance games to LLM-based agents. Effective assistance requires reasoning over human preferen…
