Multi-Granularity Position Embedding of Graphs via Granular-Ball for Link Prediction

Sen Zhao, Cheng Liu, Shuyin Xia, Zhiyuan Liu, Yi Liu, Yi Wang, et al.

Link prediction aims to identify potential or future connections within a given graph structure. Position information is essential for link prediction, as it distinguishes homogeneous nodes through their relative relationships, facilitating the accurate capture of structural patt…

Towards Faithful Graph Explanations with Synergistic Edge Effects via Granular Balls

Jiancu Chen, Shuyin Xia, Guan Wang, Degang Chen, Fan Chen

Instance-level explanations aim to reveal the rationale behind a model's decisions for a specific graph. Previous methods explain graph neural networks (GNNs) by selecting important edges to induce subgraphs, where edge importance is assessed by perturbing each edge and observing…
