Researchers have identified that self-inconsistency in explanations from Self-Interpretable Graph Neural Networks (SI-GNNs) stems from re-explanation-induced context perturbation. They propose a latent signal assignment hypothesis to explain why certain edges are more sensitive to this perturbation and how conciseness regularization impacts it. To address this, a new post-processing strategy called Self-Denoising (SD) has been developed, which improves explanation quality with minimal computational overhead. AI
