Researchers have introduced EviBall, a novel framework designed to improve few-shot classification of Whole Slide Images (WSIs). This method addresses challenges in aggregating sparse, spatially organized diagnostic cues under limited supervision by organizing local patches into class-conditioned "Evidence Balls." EviBall utilizes semantic-spatial assignment and center refinement to create coherent evidence units, which are then retrieved using task-specific queries, including language-guided and molecular-guided options. This approach reformulates WSI classification as a structured evidence retrieval and competition process, outperforming existing methods in experiments across various WSI tasks. AI
