Reinforcement Learning for Optimizing Conditional Tabular Generative Adversarial Networks Hyperparameters in Financial Fraud Detection

2024

Financial fraud datasets typically exhibit a pro-nounced class imbalance, leading to elevated false positive rates when employing machine learning classifiers. To mitigate this issue, the Conditional Tabular Generative Adversarial Network (CTGAN), an oversampling technique tailored …
