Task-Agnostic Graph Explanations

Xie, Yaochen, Katariya, Sumeet, Tang, Xianfeng et al.

Understand

Graph Neural Networks (GNNs) have emerged as powerful tools to encode graph-structured data.

  • Due to their broad applications, there is an increasing need to develop tools to explain how GNNs make decisions given graph-structured data.
  • Existing learning-based GNN explanation approaches are task-specific in training and hence suffer from crucial drawbacks.
  • Specifically, they are incapable of producing explanations for a multitask prediction model with a single explainer.
