CAR-MIL: Counterfactual Attention Regularization for Multiple Instance Learning

Imane Chraki, Pierre Marza, Stergios Christodoulidis +1

Multiple Instance Learning (MIL) is widely used for weakly supervised learning, particularly in digital pathology, where fine-grained annotations are costly. Most MIL methods aggre…

On the Cone Effect and Modality Gap in Medical Vision-Language Embeddings

David Restrepo, Miguel L Martins, Chenwei Wu +5

Vision-Language Models (VLMs) exhibit a characteristic "cone effect" in which nonlinear encoders map embeddings into highly concentrated regions of the representation space, contri…
