Mitigating Degree Biases in Message Passing Mechanism by Utilizing Community Structures

1 code implementation28 Dec 2023 Van Thuy Hoang, O-Joun Lee

In this paper, we propose Community-aware Graph Transformers, namely CGT, to learn degree-unbiased representations based on learnable augmentations and graph transformers by extracting within community structures.

Companion Animal Disease Diagnostics based on Literal-aware Medical Knowledge Graph Representation Learning

1 code implementation31 Aug 2023 Van Thuy Hoang, Sang Thanh Nguyen, Sangmyeong Lee, Jooho Lee, Luong Vuong Nguyen, O-Joun Lee

In this paper, we propose a knowledge graph embedding model for the efficient diagnosis of animal diseases, which could learn various types of literal information and graph structure and fuse them into unified representations, namely LiteralKG.
