Hello,

I have a question regarding the calculation (4.8) on p.139 in the book. The final hypothesis $g^{-}$ depends, albeit indirectly, on the choice of the validation set $\mathcal{D}_{val}$ . Indeed, by construction we train on the complement of $\mathcal{D}_{val}$ in $\mathcal{D}$ , which makes $g^{-}$ dependent on the choice of $\mathcal{D}_{val}$ . The derivation (4.8) appears to rely on the assumption that $g^{-}$ is independent of $\mathcal{D}_{val}$ .

Does anyone have any comments on this?
