In this paper, we evaluate the use of five existing error metrics as fitness functions in GP regression. The overall purpose is to investigate how the optimization of the different error metrics affects the produced model. Specifically, in the experimentation, all models, regardless of the fitness...
周期核(Periodic Kernel),也称为周期性核函数,是一种在高斯过程回归(Gaussian Process Regression, GPR)中常用的核函数,它能够模拟目标函数的周期性特征。周期核的一般形式可以表达为: \[ k(x_i, x_j) = \exp\left(-\frac{2\sin^2(\pi|x_i - x_j|/p)}{l^2}\right) \] 其中: - \( p \...
Procedures for robust initialisation and optimisation of Variational Sparse Gaussian processes. This code accompanies Burt et al (2019, 2020) (see sitation below), and implements the recommendations. The bottom line In Burt et al (2020), we recommend Sparse GP Regression (SGPR) (Titsias, 2009)...
