AI explainability research proposes new baseline for medical imaging

Researchers have introduced a new concept called "semantic missingness" for explainability methods in medical AI. This approach defines a baseline for path attribution techniques like Integrated Gradients not just as an absence of signal, but as a clinically plausible state where disease-related features are absent. The study proposes using counterfactual generative models, such as VAEs and diffusion models, to create these meaningful baselines, demonstrating improved faithfulness and medical relevance in attributions across three datasets.
