DANG: Decoupled Adaptive Normalized Graph Convolutional Network for Sign-Aware Recommendation

Graph Neural Networks (GNNs) are widely used in recommendation systems, but most methods focus solely on positive feedback, neglecting the avoidance preferences inherent in negative interactions. Although recent sign-aware methods have attempted to integrate bidirectional feedback, they suffer from two major limitation...
