Function to calculate the principal components of a kernel.

Description

Function to calculate the principal components of a kernel.

Usage

KPC(K, thr)

Arguments

K

an NxN numeric matrix with the Kernel matrix.

thr

a positive scalar which is a threshold to discard eigen-vectors based on eigen-values.

Value

the kernel principal components

Examples

x = rnorm(100,0,1)
k = RBF_K(x,1)
k_ = kernel_normal(k)
kpca = KPC(k,1e-8)
