In this study, we consider the covariates shift caused by the action on the data problem. Also, consider the method of bias correction using the density ratio estimation.In the numerical experiments, the action actually cause unsteady / extrapolation problem of distribution. It shows that have a significant bias to the expected value evaluation.Further illustrates that the method using the density ratio even in the case of changing the data size and dimensions are effective.
