近期研究论文探讨了用于复杂问题的贝叶斯优化(BO)技术的进展。一项研究介绍了“脱离循环”(Out-Of-The-Loop)MF-BO,它结合了历史高保真数据,在最高保真度直接访问成本过高时改进优化。另一篇论文提出了一种双层BO方法,该方法利用具有黑盒和白盒变量的问题中的可分离性,在基准测试中表现优于标准方法。此外,还提出了一个名为“Tempered Posteriors”的框架,通过调整高斯过程代理来增强BO的鲁棒性,在局部采样下表现出改进的性能。最后,用于超参数优化中BO的动态先验框架允许持续的用户影响,在与竞争对手的比较中持续表现优异。

arXiv:2608.00641v2 Announce Type: replace Abstract: Bayesian optimization (BO) relies on a surrogate model and an acquisition function, yet the most suitable choices vary across tasks and optimization stages. Automated Bayesian optimization (AutoBO) addresses this variability by …
arXiv:2608.04113v1 Announce Type: cross Abstract: Black-box optimization is a ubiquitous problem in science and engineering, often dealing with expensive objective functions with cheaper lower-fidelity proxies available. Multi-fidelity Bayesian optimization (MF-BO) is a principle…
