Key points
- A transaction can look harmless in isolation and suspicious once its links to recent fraud become visible.
- Rai introduces the neighborhood signal and the constraints of two transaction portfolios; Sharique then walks through sampling, graph construction, explanation and serving.
- Attribution connects a suspicious score to specific transaction edges for analyst review.
