vm-class | R Documentation |
An S4 VIRTUAL class used as a base for the various vector machine classes in kernlab
Objects from the class cannot be created directly but only contained in other classes.
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
signature(object = "vm")
: returns the complete
alpha vector (wit zero values)
signature(object = "vm")
: returns the
cross-validation error
signature(object = "vm")
: returns the training
error
signature(object = "vm")
: returns the fitted
values (predict on training set)
signature(object = "vm")
: returns the kernel
function
signature(object = "vm")
: returns the kernel
parameters (hyperparameters)
signature(object = "vm")
: returns the levels in
case of classification
signature(object="vm")
: returns the function call
signature(object = "vm")
: returns the problem type
signature(object = "vm")
: returns the data
matrix used(support vectors)
signature(object = "vm")
: returns the
response vector
