The original version of this Article contained a typo in Eq. (1), in which the subscript of \(\beta \left\| W \right\|_{{\mathrm{TV}}}\) was given incorrectly. The correct expression is \(\beta \left\| W \right\|_{l_2}\). Correspondingly, in the following text, “TV regularization of W” should be corrected as “l2 regularization of W”; “\(\beta \left\| W \right\|_{{\mathrm{TV}}}\) is used” should be corrected as “\(\beta \left\| W \right\|_{l_2}\) is used”.
