Causal Label Recovery in Payment Networks
Researchers introduce the Sequential Triply Robust (STR) estimator to correct systematic biases in payment fraud detection models caused by authorization gates, unreported fraud, chargeback delays, and label corruption. The method achieves theoretical efficiency bounds while enabling models to train on fresher data, potentially reducing the need to wait months for complete chargeback information.
