Description

Generate point-wise functions for two vectors using rbf kernel.

Usage

1
kernel_rbf(Sigma, l, p)

Arguments

Sigma

(matrix) The covariance matrix for neural network kernel.

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.

Details

k_{SE}(r)=exp\Big(-\frac{r^2}{2l^2}\Big)

Value

point_wise

(function) A function calculating the relevance of two vectors.
