New Temporal Graph Transformer Aims to Improve Credit Card Fraud Detection

By PulseAugur Editorial · [1 sources] ·

Researchers have developed THGT-FD, a Temporal Heterogeneous Graph Transformer designed for credit card fraud detection. This model represents transactions using tokens for the transaction itself and six relation types, incorporating Time2Vec encoding. Experiments on a large dataset showed THGT-FD achieved an AUC-ROC of 0.8536, though a histogram-based gradient-boosting baseline performed slightly better with an AUC-ROC of 0.8722. The study suggests that relational information is valuable for fraud risk assessment. AI

IMPACT Introduces a novel graph-based approach that could enhance the accuracy of fraud detection systems.

    Temporal Heterogeneous Graph Transformer for Credit Card Fraud Detection

    arXiv:2609.07100v1 Announce Type: cross Abstract: Credit card fraud detection typically relies on tabular features, while repeated attributes can also provide useful relational signals. This paper proposes THGT-FD, a Temporal Heterogeneous Graph Transformer for Fraud Detection. E…
