The insensitive parameter $ε>0$ changes with the sample size and plays a crucial role in the learning algorithm. The purpose of this paper is to present a perturbation theorem to show how the medium function of the probability measure for regression (with $ε=0$) can be approximated by learning the minimizer of the generalization error with sufficiently small parameter $ε>0$. A concrete learning rate is provided under a regularity condition of the medium function and a noise condition of the probability measure. rv:
