Exploring the Individuality and Collectivity of Intents behind Interactions for Graph Collaborative Filtering

no code implementations15 May 2024 Yi Zhang, Lei Sang, Yiwen Zhang

To counter the sparsity of implicit feedback, the feature distributions of users and items are encoded via a Gaussian-based graph generation strategy, and we implement the recommendation process through bilateral intent-guided graph reconstruction re-sampling.
