Evidence-Gated LLM Priors for Multi-Objective Bayesian Optimization

arXiv:2606.01730v1 Announce Type: cross Abstract: Large language models (LLMs) are increasingly used as heuristic advisors for black-box optimization, yet their suggestions and self-reported confidence are not necessarily calibrated to downstream objective values. This issue becomes more pronounced in multi-objective Bayesian optimization, where different objectives may require different expert knowledge and where an LLM expert can be useful for one objective but misleading for another. We study how to use LLM-generated expert priors in discrete multi-objective Bayesian optimization without bl

Why this matters
Why now

The paper addresses a critical current challenge in using LLMs for complex, real-world optimization problems, as their application moves beyond simple text generation to decision-making.

Why it’s important

Improving the calibration and reliability of LLM suggestions in multi-objective optimization is crucial for effectively leveraging AI in scientific discovery, engineering, and business without incurring high costs or risks from uncalibrated assumptions.

What changes

This research outlines a method to integrate LLM priors into multi-objective Bayesian optimization processes more robustly, potentially leading to more efficient and trustworthy AI-driven decision-making in complex systems.
