新的ALAS核族增强了贝叶斯优化的灵活性

研究人员推出了一种新颖的用于灵活贝叶斯优化的高斯过程核族ALAS。ALAS利用对称α-稳定谱分量,使其能够从数据中自适应其有效平滑度,以更好地建模具有平滑趋势和尖锐不规则性的目标函数。提出的核族包含两种参数化:ALAS用于具有谱调制的单平稳分量,以及ALAS-Sep用于可分离的、逐维学习,以增强可分解目标上的鲁棒性。在各种基准测试和真实世界代理模型上的实验结果表明,ALAS在不同的优化场景中提供了强大且一致的性能。 AI

影响 增强了贝叶斯技术在复杂、现实世界问题中的适应性和鲁棒性。

    ALAS:用于灵活贝叶斯优化的可加性可学习 Alpha-稳定核

    arXiv:2607.18282v1 Announce Type: new Abstract: Bayesian Optimization is widely used for expensive black-box optimization, yet its success often depends on choosing a kernel that matches the objective's unknown structure. In this work, we propose ALAS, a flexible Gaussian Process…
