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.

We confirm the planetary nature of the companion via a combination of radial velocities, which limit the mass to $< 4. 1\,\mathrm{M_J}$ $(3\sigma)$, and a clear Doppler tomography signal, which indicates a retrograde projected spin-orbit misalignment of $\lambda = -179. 7^{+3. 7}_{-3. 8}$ degrees.
