Explainable Credit Card Fraud Detection with Image Conversion

Abstract: The increase in the volume and velocity of credit card transactions causes class imbalance and concept deviation problems in data sets where credit card fraud is detected. These problems make it very difficult for traditional approaches to produce robust detection models. In this study, a different perspective has been developed for this problem and a novel approach named Fraud Detection with Image Conversion (FDIC) is proposed. FDIC handles credit card transactions as time series and transforms them into imag… Show more

“…Iwana and Uchida [27] solved the TSC problem with two different types of inputs by considering the 1D CNN method. Sinanc et al [38] used a novel approach to convert the time series into images as the input and put these inputs in a CNN classifier. They used the gradient-weighted class activation mapping method to explain their CNN efficiency.…”
