Abstract

One of the three most common forms of online fraud has been recognized as credit card fraud. Every year, these costs financial institutions billions of dollars. While the field of credit card fraud detection using machine learning algorithms has been extensively researched, numerous studies have revealed that there are still a considerable amount of false positives or false alarms. These false positives indicate people who may be denied access to products and/or services because their transactions are incorrectly classified as credit card fraud by the detection model, even though they are lawful. This ultimately leads to the objective of this proposed research. To compare and achieve the lowest possible false positive rate, the research proposes the use of different feature selection techniques such as recursive feature elimination and correlation-based feature selection, combined with machine learning algorithms such as random forest and logistic regression.
