WebNotice that we have defined a small subset of the ML language. Note too that the induction step has four different rules. When we get to induction proofs later, you'll need to do the … Webinducing variables and inducing inputs one can considerably improve GP inference over state-of-the-art methods. 2. Preliminaries and Related Works A GP defines a distribution over functions f : RD!R, for which any finite marginal follows a Gaussian distribu-tion (Rasmussen & Williams,2005). A GP is fully de-
