Suppose that we sample a large number N N N of independent random functions f i ⁣ : R → R f_i \colon \R \to \R f i ​ : R → R from a certain distribution F \Fc F and propose to solve a regression problem by choosing a linear combination f ˉ = ∑ i λ i f i . \bar{f} = \sum_i \lambda_i f_i. f ˉ ​ = i ∑ ​ λ i ​ f i ​ .
