The originally published version of this Expression of Concern has been updated to include new information raised to us by a third party. The corrected version is also presented here with the amended text in bold.

This Expression of Concern is for the above article, published online on August 2, 2018, in Wiley Online Library (wileyonlinelibrary.com) and has been published by agreement between the journal Editor-in-Chief, Dr. Witold Pedrycz, and Wiley Periodicals LLC. The Expression of Concern has been agreed due to concerns raised regarding possible misrepresentation of the data set of facial images used in this article. Based on information provided by the authors, data collection for the above mentioned article took place in 2014. However, it has subsequently been noted that images from this same data set have purportedly been used in Duan et al. (2010), Wang et al. (2018), in which the data reported was purportedly collected in 2012 and the article co-authored by the corresponding author of the above mentioned article, and Ma (2012), which acknowledges the guidance and support of the corresponding author of the above mentioned article in the student's thesis work and includes at least one similar data point to the above mentioned article in the form of a facial image. The journal therefore has concerns about when data collection actually took place. Additionally, Figure 1 in the above mentioned article appears to be the same as Figure 1 in Wang et al. (2018), though there is no citation, and permission was not obtained to reuse the figure. The authors have not provided further information to the journal to help clarify when data collection took place. As a result, the journal has decided to issue an Expression of Concern to readers.

The online version of the originally published Expression of Concern has been corrected accordingly.

本担忧表达的最初发布版本已更新，以包含第三方向我们提供的新信息。此处还提供了更正后的版本，修改后的文本以粗体显示。

本关注表针对上述文章，该文章于 2018 年 8 月 2 日在线发表于 Wiley 在线图书馆 (wileyonlinelibrary.com)，并经期刊主编 Witold Pedrycz 博士和 Wiley periodicals 同意发表有限责任公司。由于人们担心本文中使用的面部图像数据集可能被误传，因此已同意表达关注。根据作者提供的信息，上述文章的数据收集发生于 2014 年。然而，随后注意到，Duan 等人据称使用了来自同一数据集的图像。 （2010），王等人。 (2018)，据称报告的数据是在 2012 年收集的，该文章由上述文章的通讯作者合着；Ma (2012)，感谢上述文章通讯作者的指​​导和支持学生论文中的文章，并以面部图像的形式包含至少一个与上述文章类似的数据点。因此，该杂志对数据收集的实际发生时间表示担忧。此外，上述文章中的图 1 似乎与 Wang 等人的图 1 相同。 （2018），尽管没有引用，也没有获得重复使用该图的许可。作者没有向期刊提供进一步的信息来帮助澄清数据收集的时间。因此，该杂志决定向读者发出一份关注声明。

最初发布的《关注表达》的在线版本已进行了相应更正。
