Learn from Heterophily: Heterophilous Information-enhanced Graph Neural Network

no code implementations26 Mar 2024 Yilun Zheng, Jiahao Xu, Lihui Chen

Under circumstances of heterophily, where nodes with different labels tend to be connected based on semantic meanings, Graph Neural Networks (GNNs) often exhibit suboptimal performance.

LA-HCN: Label-based Attention for Hierarchical Multi-label TextClassification Neural Network

1 code implementation23 Sep 2020 Xinyi Zhang, Jiahao Xu, Charlie Soh, Lihui Chen

In this paper, we propose a Label-based Attention for Hierarchical Mutlti-label Text Classification Neural Network (LA-HCN), where the novel label-based attention module is designed to hierarchically extract important information from the text based on the labels from different hierarchy levels.
