Researchers have developed ReMoDEx, a framework designed to assess the decision-making processes of deep learning image classifiers at scale. This method combines local explainability techniques with a global module to identify and cluster common decision strategies, moving beyond single-sample heatmap inspections. When applied to a VGG16 classifier for medical imaging, ReMoDEx revealed two prevalent strategies: reliance on central thoracic regions and sensitivity to image borders, suggesting potential shortcut learning that traditional accuracy metrics might miss.
