Summary
- What is new: The discovery that complementary relationships in items involve both low-frequency and mid-frequency spectral components, and the use of spectral-based GNNs to model these relationships.
- Why this is important: Existing models fail to effectively balance relevance and dissimilarity in complementary item relationships, impacting recommendation accuracy.
- What the research proposes: A novel Spectral-based Complementary Graph Neural Network (SComGNN) that uses spectral graph convolutions with low-pass and mid-pass filters, coupled with a two-stage attention mechanism.
- Results: SComGNN significantly outperforms baseline models on four e-commerce datasets, proving its effectiveness in modeling complementary relationships.
