Webb5 jan. 2016 · Gaussian Processes. Definition A Gaussian Process is a collection of random variables, any finite number of which have consistent joint Gaussian distributions. A Gaussian process f f is fully specified by its mean function m(x) m ( x) and covariance function k(x,x0) k ( x, x 0), written as f ∼ GP(m,k) f ∼ G P ( m, k) WebbHilbert Spaces 87 If y∈ M, then kx−yk2 = kPx−yk2 +kQxk2, which is clearly minimized by taking y= Px.
