AI总结:

本研究系统评估了多保真度贝叶斯优化在材料和分子研究中的参数影响,提供了在实验环境中使用MFBO的指南,并通过合成和真实发现问题验证其相对于单保真度方法的优势。

摘要:

多保真度贝叶斯优化是一个很有前景的框架,可以加速材料和分子发现,因为不同准确度的信息源以递增的成本可用。尽管其在化学任务中有潜在用途,但目前缺乏对MFBO中起作用的众多参数的系统评估。在本研究中,我们提供了在实验环境中决定何时使用MFBO的指南和建议。我们研究了应用于分子和材料问题的MFBO方法。首先,我们在两个合成问题中测试了两个不同系列的采集函数,并研究了近似函数的信息量和成本的影响。我们使用我们的实现和指南对三个真实发现问题进行了基准测试,并将它们与单保真度对应方法进行了比较。我们的结果可能有助于指导未来在化学科学中将MFBO作为常规工具实施的努力。

英文摘要:

Multi-fidelity Bayesian Optimization (MFBO) is a promising framework to speed up materials and molecular discovery as sources of information of different accuracies are at hand at increasing cost. Despite its potential use in chemical tasks, there is a lack of systematic evaluation of the many parameters playing a role in MFBO. In this work, we provide guidelines and recommendations to decide when to use MFBO in experimental settings. We investigate MFBO methods applied to molecules and materials problems. First, we test two different families of acquisition functions in two synthetic problems and study the effect of the informativeness and cost of the approximate function. We use our implementation and guidelines to benchmark three real discovery problems and compare them against their single-fidelity counterparts. Our results may help guide future efforts to implement MFBO as a routine tool in the chemical sciences.
