Real-World Impact: Graph Transformers for WSI Classification
Problem: Traditional image analysis struggles with gigabyte-sized Whole Slide Images (WSIs), making disease diagnosis challenging due to sheer data volume and complex spatial relationships.
Solution: Graph Transformers are employed to process WSI patches as nodes in a graph. By leveraging self-attention mechanisms, the model learns complex spatial relationships and contextual information between patches for accurate classification.
Impact: This approach enables efficient and robust analysis for disease detection and classification in computational pathology, overcoming limitations of traditional methods and enhancing diagnostic capabilities.
