Researchers have introduced the Semantic-Aware Subgraph State Space Model (SASG-SSM), a novel framework designed for classifying whole slide images (WSIs) in histopathology. This model addresses limitations of traditional patch-based methods by approximating semantic units, which represent irregularly shaped tissue regions, and preserving their internal spatial organization. The SASG-SSM integrates a graph neural network for encoding intra-subgraph topology with a Mamba-based state space encoder for efficient contextualization across numerous subgraphs, thereby combining local structural and global contextual information. Experiments on four WSI subtyping datasets show significant advantages over existing state-of-the-art methods, with additional evaluations demonstrating robustness and data efficiency in small-cohort and few-shot learning scenarios.
