A retinal disease detection model that achieved 96% accuracy in lab settings failed dramatically when tested on images from a different hospital, dropping to near-random guessing. This failure highlighted the problem of "shortcut learning," where models exploit dataset-specific artifacts rather than genuine clinical features. To address this, the project shifted focus from pure accuracy to generalization by aggregating multiple public datasets with diverse acquisition parameters and patient demographics. AI
