具有函数型输出的计算机模型验证AI 解读

A key question in evaluation of computer models is Does the computer model adequately represent reality? A six-step process for computer model validation is set out in Bayarri et al. [Technometrics 49 (2007) 138–154] (and briefly summarized below), based on comparison of computer model runs with field data of the process being modeled. The methodology is particularly suited to treating the major issues associated with the validation process: quantifying multiple sources of…

非参数回归中窗口估计的一致性AI 解读

Stone proved that nearest neighbor estimates of a nonparametric regression function are "universally" consistent. We show that the same holds for window estimates, and we obtain a rate of convergence under some restrictions.
