HL-MBO: Human-in-the-Loop Meta Bayesian Optimization for Fusion Energy
The Human-in-the-Loop Meta Bayesian Optimization (HL-MBO) is a novel machine learning framework designed to enhance research in Inertial Confinement Fusion (ICF) and other scientific fields with limited data. Created by a team of researchers, HL-MBO combines expert insights with few-shot, uncertainty-aware machine learning to suggest potential experiments. It employs a meta-learned surrogate model alongside an expert-informed acquisition function, offering clear explanations to build confidence. This approach surpasses existing Bayesian optimization methods in optimizing ICF energy yield and excels in benchmarks related to molecular optimization and maximizing critical temperatures in superconducting materials. Despite its potential for sustainable clean energy, ICF faces challenges due to high costs and restricted experimental opportunities.
