SplitGNN: Spectral Graph Neural Network for Fraud Detection against Heterophily

2 code implementations • CIKM 2023 • Bin Wu, Xinyu Yao, Boyan Zhang, Kuo-Ming Chao, Yinsheng Li

However, researches on addressing the heterophily problem in the spectral domain are still limited due to a lack of understanding of spectral energy distribution in graphs with heterophily.
