Retracted Article: Surface roughness grade evaluation of milling workpiece based on deep transfer learning

Abstract

ABSTRACT We, the Editors and Publishers of Nondestructive Testing and Evaluation, have retracted the following article: Gaowei Ye, Kaihong Zhou, Qingting Ye & Fucheng Tian (2024). Surface roughness grade evaluation of milling workpiece based on deep transfer learning. Nondestructive Testing and Evaluation. DOI:10.1080/10589759.2024.2321968. After publication, the author, Gaowei Ye, requested the retraction of this article for the following reasons: the use of Figure 9 etc. without the required permissions. the function F (I), which uses captured images to calculate the average definition value, has a serious error in the formula of the algorithm F (I), resulting in data errors in the calculation of covariance, classification loss function, etc. In light of these issues and concerns about the validity of the study, the journal has agreed to retract the article. We have been informed in our decision-making by our editorial policies and the COPE guidelines. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
