Kernel functions (see ?kernels) may be multiplied by constants,
multiplied by each other, or added together.
Usage
# S3 method for class 'kernel'
x * k2
# S3 method for class 'kernel'
k1 + k2
Arguments
- x
a numeric or a kernel function
- k2
a kernel function
- k1
a kernel function
Value
A new kernel function, with class c("kernel", "function").
Examples
x = seq(-1, 1, 0.5)
k = k_rbf()
k2 = k_per(scale=0.2, period=0.3)
k_add = k2 + 0.5*k
print(k_add)
#> function (x, y)
#> {
#> k1(x, y) + k2(x, y)
#> }
#> <bytecode: 0x5603aca95570>
#> <environment: 0x5603aca98920>
#> attr(,"name")
#> [1] "per + rbf"
image(k_add(x, x))
