Identification and Estimation of the Bi-Directional MR with Some Invalid Instruments

no code implementations10 Jul 2024 Feng Xie, Zhen Yao, Lin Xie, Yan Zeng, Zhi Geng

We consider the challenging problem of estimating causal effects from purely observational data in the bi-directional Mendelian randomization (MR), where some invalid instruments, as well as unmeasured confounding, usually exist.

SF-GNN: Self Filter for Message Lossless Propagation in Deep Graph Neural Network

no code implementations3 Jul 2024 Yushan Zhu, Wen Zhang, Yajing Xu, Zhen Yao, Mingyang Chen, Huajun Chen

In SF-GNN, we define two representations for each node, one is the node representation that represents the feature of the node itself, and the other is the message representation specifically for propagating messages to neighbor nodes.

Negative Sampling with Adaptive Denoising Mixup for Knowledge Graph Embedding

1 code implementation15 Oct 2023 Xiangnan Chen, Wen Zhang, Zhen Yao, Mingyang Chen, Siliang Tang

Most existing negative sampling methods assume that non-existent triples with high scores are high-quality negative triples.

A Comprehensive Study on Knowledge Graph Embedding over Relational Patterns Based on Rule Learning

1 code implementation15 Aug 2023 Long Jin, Zhen Yao, Mingyang Chen, Huajun Chen, Wen Zhang

Though KGE models' capabilities are analyzed over different relational patterns in theory and a rough connection between better relational patterns modeling and better performance of KGC has been built, a comprehensive quantitative analysis on KGE models over relational patterns remains absent so it is uncertain how the theoretical support of KGE to a relational pattern contributes to the performance of triples associated to such a relational pattern.

Entity-Agnostic Representation Learning for Parameter-Efficient Knowledge Graph Embedding

1 code implementation3 Feb 2023 Mingyang Chen, Wen Zhang, Zhen Yao, Yushan Zhu, Yang Gao, Jeff Z. Pan, Huajun Chen

In our proposed model, Entity-Agnostic Representation Learning (EARL), we only learn the embeddings for a small set of entities and refer to them as reserved entities.

Analogical Inference Enhanced Knowledge Graph Embedding

1 code implementation3 Jan 2023 Zhen Yao, Wen Zhang, Mingyang Chen, Yufeng Huang, Yi Yang, Huajun Chen

And in AnKGE, we train an analogy function for each level of analogical inference with the original element embedding from a well-trained KGE model as input, which outputs the analogical object embedding.
