Knowledge-Enhanced Explainable Hypergraph Convolution Network for Medication Recommendation

AAAI 2026technical

Medication recommendation systems aim to provide personalized and safe medication options based on individual patient records. However, existing approaches often face challenges related to inadequate modeling of complex relationships within Electronic Health Records (EHRs), data sparsity, and a lack

Towards a More Stable and General Subgraph Information Bottleneck

ICASSP 2023accepted

Graph Neural Networks (GNNs) have been widely applied to graph-structured data. However, the lack of interpretability impedes its practical deployment especially in high-risk areas such as medical diagnosis. Recently, the Information Bottleneck (IB) principle has been extended to GNNs to identify a…

AiM: Taking Answers in Mind to Correct Chinese Cloze Tests in Educational Applications

COLING 2022main

To automatically correct handwritten assignments, the traditional approach is to use an OCR model to recognize characters and compare them to answers. The OCR model easily gets confused on recognizing handwritten Chinese characters, and the textual information of the answers is missing during the mo…

Seeking Patterns, Not just Memorizing Procedures: Contrastive Learning for Solving Math Word Problems

ACL 2022findings

Math Word Problem (MWP) solving needs to discover the quantitative relationships over natural language narratives. Recent work shows that existing models memorize procedures from context and rely on shallow heuristics to solve MWPs. In this paper, we look at this issue and argue that the cause is a…

Relation-Aware Neighborhood Matching Model for Entity Alignment

AAAI 2021technical

Entity alignment which aims at linking entities with the same meaning from different knowledge graphs (KGs) is a vital step for knowledge fusion. Existing research focused on learning embeddings of entities by utilizing structural information of KGs for entity alignment. These methods can aggregate…

Spiral Generative Network for Image Extrapolation

ECCV 2020poster

In this paper, motivated by human natural ability to perceive unseen surroundings imaginatively, we propose a novel Spiral Generative Network, SpiralNet, to perform image extrapolation in a spiral manner, which regards extrapolation as an evolution process growing from an input sub-image along a spi…
