Generating Robust Counterfactual Witnesses for Graph Neural Networks

no code implementations30 Apr 2024 Dazhuo Qiu, Mengying Wang, Arijit Khan, Yinghui Wu

Given a graph neural network M, a robust counterfactual witness refers to the fraction of a graph G that are counterfactual and factual explanation of the results of M over G, but also remains so for any "disturbed" G by flipping up to k of its node pairs.

View-based Explanations for Graph Neural Networks

1 code implementation4 Jan 2024 Tingyang Chen, Dazhuo Qiu, Yinghui Wu, Arijit Khan, Xiangyu Ke, Yunjun Gao

Existing approaches aim to understand the overall results of GNNs rather than providing explanations for specific class labels of interest, and may return explanation structures that are hard to access, nor directly queryable. We propose GVEX, a novel paradigm that generates Graph Views for EXplanation.
