- Abstract: Credit card fraud is an ongoing problem for almost all industries in the
world, and it raises millions of dollars to the global economy each year.
Therefore, there is a number of research either completed or proceeding in
order to detect these kinds of frauds in the industry. These researches
generally use rule-based or novel artificial intelligence approaches to find
eligible solutions. The ultimate goal of this paper is to summarize
state-of-the-art approaches to fraud detection using artificial intelligence
and machine learning techniques. While summarizing, we will categorize the
common problems such as imbalanced dataset, real time working scenarios, and
feature engineering challenges that almost all research works encounter, and
identify general approaches to solve them. The imbalanced dataset problem
occurs because the number of legitimate transactions is much higher than the
fraudulent ones whereas applying the right feature engineering is substantial
as the features obtained from the industries are limited, and applying feature
engineering methods and reforming the dataset is crucial. Also, adapting the
detection system to real time scenarios is a challenge since the number of
credit card transactions in a limited time period is very high. In addition, we
will discuss how evaluation metrics and machine learning methods differentiate
among each research.

There is a certain consensus about the need to develop AI applications with a Human-Centric approach.
Human-Centric Machine Learning needs to be developed based on four main requirements: (i) utility and social good; (ii) privacy and data ownership; (iii) transparency and accountability; and (iv) fairness in AI-driven decision-making processes.
We study how current multimodal algorithms based on heterogeneous sources of information are affected by sensitive elements and inner biases in the data.
