Description Format Value Methods Public fields Methods Author(s)

Description

This a abstract class provide the kernel function and the 1st order derivative of rbf kernel function.

Format

R6Class object.

Value

an R6Class object which can be used for the rkhs interpolation.

Methods

kern(t1,t2)

This method is used to calculate the kernel function given two one dimensional real inputs.

dkd_kpar(t1,t2)

This method is used to calculate the gradient of kernel function against the kernel hyper parameters given two one dimensional real inputs.

dkdt(t1,t2)

This method is used to calculate the 1st order derivative of kernel function given two one dimensional real inputs.

Public fields

k_par

vector(of length n_hy) containing the hyper-parameter of kernel. n_hy is the length of kernel hyper parameters.
