Risk-Conditioned Fine-Tuning of Large Language Models

Zixuan Liu, Fangzheng Wu, Brian Summa +2

Large Language Models (LLMs) are increasingly deployed in settings where rare but severe harmful generations can have significant consequences. Existing Risk-Averse RLHF addresses…

Adaptive Multilevel Twisted Sequential Monte Carlo for Rare Events Estimation in Language Models

Zixuan Liu, Fangzheng Wu, Brian Summa +1

Rare unsafe behaviors in large language models can remain practically significant even when their probability is extremely small, particularly at deployment scales involving millio…

Robust General Utility for Reinforcement Learning

Zixuan Liu, Fangzheng Wu, Brian Summa +1

Reinforcement learning (RL) with general utility extends classic RL by optimizing an arbitrary utility functional of the policy-induced occupancy measure, thereby enabling a broade…
