Modeling Whole-Slide Images as Dynamic Tumor Microenvironment Fields

Due to the gigapixel-scale nature of whole-slide images (WSIs), weakly supervised WSI analysis is commonly formulated as a multiple instance learning (MIL) problem, where patch-level features are aggregated into slide-level representations. However, diagnostic and prognostic evidence often arises from spatially coheren...

From Patches to Evidence Balls: Class-Conditioned Evidence Retrieval for Few-Shot Whole Slide Image Classification

EviBall reformulates few-shot WSI classification as structured evidence retrieval and competition among candidate classes, and reduces the reliance on learning an unconstrained global aggregation mechanism from scarce slide-level labels.
