Abstract
Fraud has become a growing concern in digital financial systems due to the rapid expansion of online transactions and digital services. Traditional rule-based systems often fail to detect sophisticated and evolving fraudulent activities. This review paper explores how machine learning techniques are transforming fraud detection by enabling systems to learn patterns, adapt to new threats, and improve accuracy over time. It provides an overview of commonly used algorithms such as decision trees, logistic regression, support vector machines, and deep learning models. The paper also discusses data challenges, including class imbalance and data privacy, along with evaluation metrics used to measure model performance. Furthermore, recent advancements such as real-time fraud detection, cloud-based deployment, and explainable AI are highlighted. The study concludes that machine learning offers a powerful and scalable solution for detecting fraud, although challenges remain in terms of interpretability and evolving attack strategies.
