In SLGP: Spatial Logistic Gaussian Process for Field Density Estimation

Initialize parameters basis functions based on Random Fourier Features

Description

Draws parameters for standard RFF approximating a Matérn kernel.

Usage

initialize_basisfun_RFF(dimension, nFreq, MatParam = 5/2, lengthscale)

Arguments

dimension	Integer. Input ([\mathbf{x},\,t]) dimension.
nFreq	Integer. Number of frequency vectors to be considered.
MatParam	Numeric. Matérn smoothness parameter (default = 5/2).
lengthscale	Numeric vector. Lengthscales used for scaling the input space.

Value

List with frequency, offset, and coefficient parameters.
