Default calculation 4.8 on p.139


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?
