Neuro-Symbolic Fraud Detection: Catching Concept Drift Before F1 Drops (Label-Free)

This Article asks what happens next. The model has encoded its knowledge of fraud as symbolic rules. V14 below a threshold means fraud. What happens when that relationship starts to change? Can the rules act as a canary? In other words: can neuro-symbolic concept drift monitoring work at inference time, without labels?
