新的导数高斯过程方法降低了计算成本

研究人员开发了一种新的导数高斯过程(GP)方法,该方法显著降低了纳入梯度观测值的计算成本。该方法每梯度仅使用两个方向的预算,专注于对目标预测的直接和间接贡献。当与Vecchia近似相结合时,该方法在实现与现有精确梯度缩减技术相当的准确性的同时,所需的时间和内存大大减少,甚至优于仅函数GP基线。 AI

影响 这项研究可能导致更高效、更准确的机器学习代理模型,并可能影响需要复杂模拟或优化的领域。

    双向预算上的导数高斯过程

    arXiv:2610.10428v1 Announce Type: cross Abstract: Gradient observations promise more accurate Gaussian process (GP) surrogates, but the cost of incorporating them has long stood in the way of realizing that promise. We propose a derivative GP with a budget of just two directions …
