In the article titled “Research on Credit Card Default Prediction Based on k-Means SMOTE and BP Neural Network” [1], the authors would like to clarify that they employed the python package, kmeans-smote 0.1.2, in this study [2]. The error is that a citation to the related article was not included in the original publication, and the following text in Section 3 should be replaced with the addition of the missing references, 22 and 23 [2, 3]:

“Therefore, according to the problem of imbalance of credit card sample categories, this paper uses an improved smote algorithm called k-means SMOTE algorithm” should be replaced with “Therefore, according to the problem of imbalance of credit card sample categories, this paper uses an improved smote algorithm called k-means SMOTE algorithm [22, 23].”
