New Coactive learning method optimizes autonomous materials discovery

Researchers have developed a new method called Coactive learning for autonomous materials discovery, which combines cost-sensitive Bayesian hypothesis discrimination with Gaussian-process Bayesian optimization. This approach aims to efficiently identify the most promising recovery pathway for optimization within an autonomous laboratory setting, considering heterogeneous experimental costs. The method was evaluated on synthetic benchmarks inspired by studies from Pacific Northwest National Laboratory and demonstrated comparable performance to an oracle-pathway reference and a strong baseline, successfully avoiding suboptimal pathway selections.
