Researchers have developed a new framework called Hierarchical Prototype-based Domain Priors (HPDP) to improve the analysis of histopathology images in digital pathology. This approach addresses limitations in existing methods by incorporating morphological semantics and spatial geometry, which are often lost in current Multiple Instance Learning frameworks. HPDP utilizes a Morphologically Anchored Prototype System (MAPS) and a Sinusoidal Positional Encoder (SPE) to enhance interpretability and model tissue architecture, while a Hierarchical Cross-Modal Alignment (HCMA) module bridges visual and semantic gaps using LLM-generated descriptions. Experiments across seven cancer cohorts show HPDP achieving state-of-the-art performance with increased robustness and interpretability. AI
