High-Dimensional Bayesian Optimization via Additive Models with Overlapping Groups

2018 · arXiv (Cornell University)

Bayesian optimization (BO) is a popular technique for sequential black-box function optimization, with applications including parameter tuning, robotics, environmental monitoring, and more. One of the most important challenges in BO is the development of algorithms …

On Almost Surely Safe Alignment of Large Language Models at Inference-Time

2025 · arXiv (Cornell University)

We introduce a novel inference-time alignment approach for LLMs that aims to generate safe responses almost surely, i.e., with probability approaching one. Our approach models the generation of safe responses as a constrained Markov Decision …
