Module Cov_lin_ard

module Cov_lin_ard: sig .. end
Covariance of linear functions with Automatic Relevance Determination



The covariance is defined as:

k(x, y) = x*inv(P)*y

where P is a diagonal matrix containing ARD parameters ell_1^2,...,ell_D^2, and D is the dimensionality of the input space.
