The build in kernel classes in kernelab
Objects can be created by calls of the form new("rbfkernel", ...),
new{"polykernel"}, new{"tanhkernel"},
new{"vanillakernel"}
or by calling the rbfdot, polydot, tanhdot,
vanilladot functions.
.Data:"function" containing
the kernel function kpar:"list" containing the
kernel parameters
Class "kernel", directly.
Class "function", by class "kernel".
signature(kernel = "rbfkernel", x =
"matrix"): computes the kernel matrix signature(kernel = "rbfkernel", x =
"matrix"): computes the quadratic kernel expressionsignature(kernel = "rbfkernel", x =
"matrix"): computes the kernel expansion
