Abstract: This study introduces WideGCN, a novel recommendation system that goes beyond historical user-product interactions to incorporate user and product side information. Unlike traditional NGCF and LGCN methods, WideGCN uses two fully connected neural networks to extract features for users and products, respectively. These features are then integrated with representations learned from LightGCN to produce final user and product representations. Compared to baselines like Popularity, BPR, NGCF, and LGCN, WideGCN consistently achieves higher validation scores and faster training speeds, demonstrating the effectiveness of incorporating side information for enhanced recommendation performance.
