English(EN) Scalable Krylov Subspace Methods for Generalized Mixed-Effects Models with Crossed Random Effects

新的Krylov方法加速混合效应模型计算

研究人员开发了新的基于Krylov子空间的方法,以显著加速广义混合效应模型的计算,特别是那些具有高维交叉随机效应的模型。与传统的Cholesky分解技术相比,这些新方法提供了几个数量级的加速和改进的计算鲁棒性。所提出的方法在准确性上与现有方法基本相同,并通过理论和实证进行了分析,并应用于模拟和真实世界数据。 AI

影响 这些计算进步可以使AI和机器学习研究中更有效地分析复杂数据集。
