New LAGO framework blends Bayesian and trust region optimization

Researchers have developed LAGO, a novel framework that combines Bayesian Optimization with gradient-based trust region methods for optimizing expensive-to-evaluate functions. This approach adaptively balances global exploration with local refinement, proposing candidate points from both strategies and selecting the next evaluation based on predicted improvement. LAGO aims to enhance Bayesian Optimization by efficiently refining solutions in promising areas while maintaining exploratory behavior when local steps are less competitive, and it incorporates a mechanism to reduce numerical instability.
