It is impossible to minimize both simultaneously.

Gradient descent is applied to the new training set. It is a foundational element of logic and human reasoning. Generalizations posit the existence of a domain or set of elements, as well as one or more common characteristics shared by those elements. Learning theory: stability is sufficient for generalization and necessary and sufficient for consistency of empirical risk minimization.

Lugosi (1996). As the goal of a learning machine is to minimize the entire quantity $G_ N$, this decomposition could appear as a useless theoretical exercise. Numbers correspond to the affiliation list which can be exposed by using the show more link. Mukherjee, P.
