kha-class: Class "kha"

Description Objects objects of class "kha" Slots Methods Author(s) See Also Examples

Description

The Kernel Hebbian Algorithm class

Objects objects of class "kha"

Objects can be created by calls of the form new("kha", ...). or by calling the kha function.

Slots

pcv:

Object of class "matrix" containing the principal component vectors

eig:

Object of class "vector" containing the corresponding normalization values

eskm:

Object of class "vector" containing the kernel sum

kernelf:

Object of class "kfunction" containing the kernel function used

kpar:

Object of class "list" containing the kernel parameters used

xmatrix:

Object of class "matrix" containing the data matrix used

kcall:

Object of class "ANY" containing the function call

n.action:

Object of class "ANY" containing the action performed on NA

Methods

eig

signature(object = "kha"): returns the normalization values

kcall

signature(object = "kha"): returns the performed call

kernelf

signature(object = "kha"): returns the used kernel function

pcv

signature(object = "kha"): returns the principal component vectors

eskm

signature(object = "kha"): returns the kernel sum

predict

signature(object = "kha"): embeds new data

xmatrix

signature(object = "kha"): returns the used data matrix
