Its content is demonstration material only: readers should ignore whether the demo content is correct.</p> <p>Step sizes in deep learning are chosen as if the loss were smooth in its parameters, and that is an assumption, not a theorem. It is the smoothness postulate: the gradient does not change arbitrarily fast, so a small step in parameter space produces a predictable change in loss.</p>
