Individual and Structural Graph Information Bottlenecks for Out-of-Distribution Generalization

1 code implementation28 Jun 2023 Ling Yang, Jiayi Zheng, Heyuan Wang, Zhongyi Liu, Zhilin Huang, Shenda Hong, Wentao Zhang, Bin Cui

To remove class spurious feature caused by distribution shifts, we propose Individual Graph Information Bottleneck (I-GIB) which discards irrelevant information by minimizing the mutual information between the input graph and its embeddings.

Spatial Autoregressive Coding for Graph Neural Recommendation

no code implementations19 May 2022 Jiayi Zheng, Ling Yang, Heyuan Wang, Cheng Yang, Yinghong Li, Xiaowei Hu, Shenda Hong

To adequately leverage neighbor proximity and high-order information, we design a novel spatial autoregressive paradigm.

Fine-grained Interest Matching for Neural News Recommendation

no code implementations ACL 2020 Heyuan Wang, Fangzhao Wu, Zheng Liu, Xing Xie

Existing studies generally represent each user as a single vector and then match the candidate news vector, which may lose fine-grained information for recommendation.
