Abstract(in English) | In this paper, we introduced a positive scaling for soft-thresholding estimators in a non-parametric orthogonal regression problem. Under LARS (least angle regression) based soft-thresholding, we first gave a risk (generalization error) for a fixed scaling. We then showed that an optimal scaling value that minimizes the risk under a sparseness condition is 1+O(√ |
