RaCMC: Residual-Aware Compensation Network with Multi-Granularity Constraints for Fake News Detection

no code implementations24 Dec 2024 Xinquan Yu, Ziqi Sheng, Wei Lu, Xiangyang Luo, Jiantao Zhou

To address this, we present a residual-aware compensation network with multi-granularity constraints (RaCMC) for fake news detection, that aims to sufficiently interact and fuse cross-modal features while amplifying the differences between real and fake news.
