Abstract—With the development of e-commerce, credit card
fraud is also increasing. At the same time, the way of credit card
fraud is also constantly innovating. Support Vector Machine,
Logical Regression, Random Forest, Naive Bayes and other
algorithms are often used in credit card fraud identification.
However, the current fraud detection technology is not accurate,
and may cause significant economic losses to cardholders and
banks. This paper will introduce an innovative method to
optimize the support vector machine by cuckoo search
algorithm to improve its ability of identifying credit card fraud.
Cuckoo search algorithm improves classification performance
by optimizing the parameters of support vector machine kernel
function (C, g). The results demonstrate that CS-SVM is
superior to SVM in Accuracy, Precision, Recall, F1-score, AUC,
and superior to Logistic. Regression, Random Forest, Decision
Tree, Naive Bayes, whose accuracy is 98%.
Index Terms—Credit card fraud, fraud detection technique, SVM, CS.
