Researchers have developed a new semi-supervised deep learning framework for credit card fraud detection, addressing challenges with large datasets and irregular transaction data. The system integrates Generative Adversarial Networks (GANs) for data augmentation, Bayesian inference for uncertainty quantification, and log-signatures for robust feature encoding. Evaluated on the BankSim dataset, the approach demonstrated improved performance over benchmarks, particularly in scenarios with limited labeled data, highlighting the value of uncertainty-aware predictions in financial time series classification.
