– ABSTRACT
Introduction: In the ever-evolving landscape of financial transactions, safeguarding against credit card fraud is imperative. This paper presents a comprehensive analysis employing machine learning techniques to enhance credit card fraud detection.
Current Landscape: Existing fraud detection systems often fall short due to their reliance on rule-based models. Recognizing this limitation, our research delves into the potential of machine learning algorithms to adapt dynamically to emerging fraudulent patterns.
Methodology: Utilizing a diverse dataset encompassing genuine and fraudulent transactions, our study employs supervised learning techniques, including logistic regression and random forests, to train the model. The active learning approach facilitates ongoing refinement as the system encounters new instances.
Feature Engineering: To bolster the model’s efficacy, we employ advanced feature engineering, considering variables such as transaction frequency, location, and user behavior. This multifaceted approach enables the model to discern subtle anomalies indicative of fraudulent activities.
Algorithmic Transparency: An essential aspect of our methodology is the emphasis on algorithmic transparency. By leveraging interpretable machine learning models, such as decision trees, we ensure that the reasoning behind fraud predictions is accessible and comprehensible.
Real-time Implementation: Unlike traditional systems with delayed response times, our model operates in real-time, swiftly identifying and flagging suspicious transactions. This proactive approach minimizes potential losses and enhances the overall security of credit card transactions.
Evaluation Metrics: The effectiveness of our model is assessed through a rigorous evaluation process, incorporating metrics like precision, recall, and F1 score. These metrics provide a holistic understanding of the model’s performance, ensuring a balanced approach to fraud detection.
Conclusion: In conclusion, our comprehensive analysis demonstrates the efficacy of machine learning in fortifying credit card fraud detection. This research contributes to the ongoing efforts to create a secure and resilient financial ecosystem.
