WebJul 1, 2024 · Gaussian processes remain popular as a flexible and expressive model class, but the computational cost of kernel hyperparameter optimization stands as a major limiting factor to their scaling and broader adoption. Recent work has made great strides combining stochastic estimation with iterative numerical techniques, essentially boiling down GP … WebB. GP Hyperparameter Learning. In GP regression, a function f (x) with desired properties, such as smoothness and periodicity, can be learned from data by a proper choice of covariance function [].For example, if f (x) is stationary (i.e., the joint probability distribution of f (x) and f (x ′) does not change when x and x ′ are translated simultaneously) …
