Harnessing logic heterograph learning for financial operational risks: A perspective of cluster and thin-tailed distributions

Guanyuan Yu, Boyu Han, Qing Li, Jiwen Huang

Abstract: Highlights•Develop a HenDen that integrates operational logic for identifying risks.•Use a HEN module to operational logic graphs into a low-dimensional space.•Apply a DEN module for unsupervised risk identification in financial datasets.•Build a joint objective function to enhance both the HEN and DEN modules.
