Project background.

Credit card fraud is a prevalent and costly problem affecting individuals, businesses, and financial institutions worldwide. According to industry reports, credit card fraud resulted in billions of dollars in losses annually. The increasing sophistication of fraudulent techniques, coupled with the rising volume of online transactions, highlights the urgent need for effective credit card fraud detection solutions. By developing accurate and efficient machine learning models, we can detect fraudulent transactions in real-time, minimize financial losses, protect customers’ assets, and maintain trust in the credit card ecosystem.

The problem.

The objective of the project is to develop an AI-based credit card fraud detection system that can accurately identify and prevent fraudulent transactions in real-time, thereby reducing financial losses and ensuring the security of credit card users and financial institutions.

Project goals.

- Develop and implement an advanced AI model for credit card fraud detection using machine learning techniques, such as deep learning or ensemble methods. - Train the AI model on a comprehensive dataset of labeled credit card transactions, ensuring a balanced representation of both fraudulent and legitimate transactions. - Optimize the AI model's performance by achieving a high accuracy rate, aiming for a minimum accuracy score of 95% to effectively detect fraudulent transactions. - Continuously improve the AI model's performance by fine-tuning hyperparameters, exploring different feature engineering techniques, and leveraging advanced anomaly detection algorithms. - Foster a learning challenge around credit card fraud detection, encouraging participants to explore innovative approaches, share insights, and contribute to state-of-the-art in fraud detection research.
