Description
Principal component analysis of a kernel is a nonlinear form related to the fundamentalComponent analysis.
Use
Method # S4 for formulaskpca (x, = data NULL, na.action, ...)# S4 method for matrixkpca (x, kernel = Kpar "rbfdot", = list (sigma = 0,1), = features 0, th means 1e4, na.action = na.omit, ...)
# s4 method for kernelMatrixkpca (x, features is 0, th = 1e4, ...)
# S4 method for listkpca (x, kernel is "stringdot", = kpar list (length = 4, lambda is 0.5), equals 0, th = 1e4, na.action means na.omit, ...)
Arguments
x
the data matrix found for each row, or a formula containing Model or just a kernel matrix with the speed kernelMatrix
or a list of charm vectors
data
optional frame data with reasons inSimulate this (if formula).
Kernel
kernel function used in learning predictions and. This parameter can be set with any kernel class function that computes the dot product with respect to two Vector arguments. kernlab offers the most common kernel featureswhich can be used very well by setting a kernel parameter to be as follows Channels:

rbfdot
The core of the radial basis follows the “Gaussian” 
polydot
Kernel polynomial function 
vanilladot
Linear Kernel Function 
tanhdot
Tangent hyperbolic kernel function 
Laplacedot
Laplace kernel function 
besseldot
Bessel kernel function 
anovadot
RBF Anova core function 
splinedot
Spline kernel
A kernel parameter can sometimes refer to a single UDF. can be customized Kernel class by passing part of the function name as an argument.
kpar
hyperparameters report (kernel parameters). Here is a list of the types of parameters used The main function. Valid parameters for existing corn kernels:

sigma
reverse kernel for larger radial base Kernel function “rbfdot” as well as Laplace kernel “laplacedot”. 
Degree, scale, offset
relative to the kernel of the “polydot” polynomial 
Scale, offset
relative to the core of the hyperbolic tangent Successes with “tanhdot” 
Sigma, order, degree
for the Bessel kernel “besseldot”. 
Sigma, degree
, which is for ANOVA core “anovadot”.
Hyperparameter users for specific kernels are easily accessible via kpar parameters also.

A working kernel used in training and therefore in forecasting. This parameter can also be set for any function linkednoah with a kernel class that computes dept. product moved between two Vector arguments. kernlab offers many common kernel features sometimes it can be used with a kernel parameter, usually like this Channels:

rbfdot

A kernel parameter can also be a userdefined parameter Program the kernel by passing the name of the function with one argument.
