Towards Faithful Graph Explanations with Synergistic Edge Effects via Granular Balls
TL;DR
SeeExplainer is a new method for interpreting graph neural networks (GNNs) that captures the synergistic effects of edges by using a granular-ball graph refinement mechanism. It outperforms existing methods in generating accurate instance-level explanations for graph classification tasks.
✦ Why It Matters
Implement SeeExplainer to improve the interpretability of your GNN models today.
Key Takeaways
- Use SeeExplainer for better GNN interpretability.
- Leverage granular-ball refinement for edge interactions.
- Generate more accurate instance-level explanations.
- Test SeeExplainer on your graph classification tasks.
How It Works
SeeExplainer refines graphs by creating granular-balls, which are clusters of nodes that vary in size. This allows for a more nuanced understanding of edge interactions.
By perturbing these nodes and edges, the method generates explanatory subgraphs that reflect the contributions of each component, leading to more accurate interpretations of model decisions.
