lssvm-class: Class "lssvm"

In elad663/kernlab: Kernel-Based Machine Learning Lab

Description

The Gaussian Processes object

Objects from the Class

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

Slots

param:

Object of class "list" contains the regularization parameter used.

kcall:

Object of class "call" contains the used function call

type:

Object of class "character" contains type of problem

coef:

Object of class "ANY" contains the model parameter

terms:

Object of class "ANY" contains the terms representation of the symbolic model used (when using a formula)

xmatrix:
