The authors would like to make the following correction of [1]:

Text Correction

In the original article, there was a mistake in Equation (8) as published. There should not be the third term

\sum_{i = 1}^{p - 1} \sum_{j = i + 1}^{p} a_{l, i} \cdot a_{l, j} \cdot e_{l, i} \cdot e_{l, j}

, as it is a repetition of the second term in Equation (7). The corrected Equation (8) appears below.

x = \sum_{i = 1}^{p} a_{l, i} \cdot e_{l, i} + \sum_{i = 1}^{p} a_{s, i} \cdot e_{s, i}

(8)

The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.

In the original article, there was a mistake in Equations (9)–(11) as published. The underline symbol “_” should not be used to represent the subscript, because it is not a unified mathematical expression compared with other equations in the paper.

The corrected Equation (9) appears below.

x_{restore} = \sum_{i = 1}^{p} (a_{l, i} + a_{s, i}) \cdot e_{l, i} + \sum_{i = 1}^{p - 1} \sum_{j = i + 1}^{p} a_{l, i} \cdot a_{l, j} \cdot e_{l, i} \cdot e_{l, j}

(9)

The corrected Equation (10) appears below.

x = \sum_{i = 1}^{p} a_{s, i} \cdot e_{s, i}

(10)

The corrected Equation (11) appears below.

x = \sum_{i = 1}^{p} a_{l, i} \cdot e_{l, i} + \sum_{i = 1}^{p - 1} \sum_{j = i + 1}^{p} a_{l, i} \cdot a_{l, j} \cdot e_{l, i} \cdot e_{l, j}

(11)

The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.
