Credit Card Fraud Detection using Machine Learning: A Study
This is an incremental review paper that summarizes known methods for detecting fraud in financial transactions, aimed at researchers or practitioners in the field.
The paper reviews existing machine learning methods for credit card fraud detection, analyzing techniques like Hidden Markov Models, Decision Trees, and Neural Networks, and concludes with a discussion of their pros and cons.
As the world is rapidly moving towards digitization and money transactions are becoming cashless, the use of credit cards has rapidly increased. The fraud activities associated with it have also been increasing which leads to a huge loss to the financial institutions. Therefore, we need to analyze and detect the fraudulent transaction from the non-fraudulent ones. In this paper, we present a comprehensive review of various methods used to detect credit card fraud. These methodologies include Hidden Markov Model, Decision Trees, Logistic Regression, Support Vector Machines (SVM), Genetic algorithm, Neural Networks, Random Forests, Bayesian Belief Network. A comprehensive analysis of various techniques is presented. We conclude the paper with the pros and cons of the same as stated in the respective papers.
