1 | kernel_rational(l, p, sigma)
|
l |
(numeric) A numeric number indicating the hyperparameter (flexibility) of a specific kernel. |
p |
(integer) For polynomial, p is the power; for matern, v = p + 1 / 2; for rational, alpha = p. |
sigma |
(numeric) The covariance coefficient for neural network kernel. |
Rational Quadratic Kernels
k_{RQ}(r)=\Big(1+\frac{r^2}{2α l^2}\Big)^{-α}
matrix_wise |
(function) A function calculating the relevance of two matrices. |
