摘要:

贝叶斯优化是一种强有力的工具,以优化黑盒函数,其中的评估是耗时或昂贵的。在本文中,我们提出了一种新的贝叶斯优化方法称为GP-MGC,它最大化多尺度图相关性的全局最大值,以确定下一个查询点。我们在涉及合成基准函数和真实数据集的应用中对GP-MGC进行了评估,并证明GP-MGC的性能与最大值熵搜索和GP-UCB等最先进的方法一样好,甚至更好。

英文摘要:

Bayesian optimization is a powerful tool to optimize a black-box function, the evaluation of which is time-consuming or costly. In this paper, we propose a new approach to Bayesian optimization called GP-MGC, which maximizes multiscale graph correlation with respect to the global maximum to determine the next query point. We present our evaluation of GP-MGC in applications involving both synthetic benchmark functions and real-world datasets and demonstrate that GP-MGC performs as well as or even better than state-of-the-art methods such as max-value entropy search and GP-UCB.
