Structure-aware Semantic Node Identifiers for Learning on Graphs

no code implementations26 May 2024 Yuankai Luo, Qijiong Liu, Lei Shi, Xiao-Ming Wu

We present a novel graph tokenization framework that generates structure-aware, semantic node identifiers (IDs) in the form of a short sequence of discrete codes, serving as symbolic representations of nodes.

Decoy Effect In Search Interaction: Understanding User Behavior and Measuring System Vulnerability

no code implementations27 Mar 2024 Nuo Chen, Jiqun Liu, Hanpei Fang, Yuankai Luo, Tetsuya Sakai, Xiao-Ming Wu

This study examines the decoy effect's underexplored influence on user search interactions and methods for measuring information retrieval (IR) systems' vulnerability to this effect.

Improving Self-supervised Molecular Representation Learning using Persistent Homology

1 code implementation NeurIPS 2023 Yuankai Luo, Lei Shi, Veronika Thost

Self-supervised learning (SSL) has great potential for molecular representation learning given the complexity of molecular graphs, the large amounts of unlabelled data available, the considerable cost of obtaining labels experimentally, and the hence often only small training datasets.

Enhancing Graph Transformers with Hierarchical Distance Structural Encoding

1 code implementation22 Aug 2023 Yuankai Luo, Hongkang Li, Lei Shi, Xiao-Ming Wu

Empirically, we demonstrate that graph transformers with HDSE excel in graph classification, regression on 7 graph-level datasets, and node classification on 11 large-scale graphs, including those with up to a billion nodes.
