Description
An S4 VIRTUAL class used as a base for the various vector
machine classes in kernlabObjects from the Class
Objects from the class cannot be created directly but only contained
in other classes.Slots
alpha:- Object of class
"listI" containing the
resulting alpha vector (list in case of multiclass classification) (support vectors) type:- Object of class
"character" containing
the vector machine type e.g.,
("C-svc", "nu-svc", "C-bsvc", "spoc-svc",
"one-svc", "eps-svr", "nu-svr", "eps-bsvr") kernelf:- Object of class
"function" containing
the kernel function kpar:- Object of class
"list" containing the
kernel function parameters (hyperparameters) kcall:- Object of class
"call" containing the function call terms:- Object of class
"ANY" containing the
terms representation of the symbolic model used (when using a formula) xmatrix:- Object of class
"input" the data
matrix used during computations (support vectors) (possibly scaled and without NA) ymatrix:- Object of class
"output" the response matrix/vector fitted:- Object of class
"output" with the fitted values,
predictions using the training set. lev:- Object of class
"vector" with the levels of the
response (in the case of classification) nclass:- Object of class
"numeric" containing
the number of classes (in the case of classification) error:- Object of class
"vector" containing the
training error cross:- Object of class
"vector" containing the
cross-validation error n.action:- Object of class
"ANY" containing the
action performed for NA
Methods
- alpha
signature(object = "vm"): returns the complete
alpha vector (wit zero values)- cross
signature(object = "vm"): returns the
cross-validation error - error
signature(object = "vm"): returns the training
error - fitted
signature(object = "vm"): returns the fitted
values (predict on training set) - kernelf
signature(object = "vm"): returns the kernel
function- kpar
signature(object = "vm"): returns the kernel
parameters (hyperparameters)- lev
signature(object = "vm"): returns the levels in
case of classification - kcall
signature(object="vm"): returns the function call- type
signature(object = "vm"): returns the problem type- xmatrix
signature(object = "vm"): returns the data
matrix used(support vectors)- ymatrix
signature(object = "vm"): returns the
response vector
