Introduction & Challenges
AINet Methodology
Experimental Results
Whole Slide Images (WSIs) are critical for cancer diagnosis, but their gigapixel scale and heterogeneous tumor distributions pose significant challenges for deep learning methods. Traditional Multi-Instance Learning (MIL) often struggles with sparse, diverse tumor regions, leading to suboptimal feature aggregation and computational burden. AINet proposes a novel solution by focusing on identifying 'Anchor Instances' (AIs) to act as semantic references, improving both local representation and global discriminability.
AINet addresses WSI heterogeneity through two core modules: the Dual-level Anchor Mining (DAM) and the Anchor-guided Region Correction (ARC). DAM identifies AIs by evaluating instance similarity to both local region embeddings and global bag embeddings. ARC then leverages these AIs to refine regional representations, ensuring discriminative power and comprehensive representativeness, while filtering out redundant information via a mask-based attention mechanism.
Extensive experiments on TCGA-BRCA, TCGA-ESCA, and BRACS datasets demonstrate AINet's superior performance compared to state-of-the-art MIL methods. It achieves significant accuracy and AUC gains with substantially fewer FLOPs and parameters. This efficiency and effectiveness highlight AINet's potential for real-world clinical applications where resource optimization is critical.

Case Study: Enhancing Breast Cancer Diagnosis
In a critical application on the TCGA-BRCA dataset, AINet demonstrated an average accuracy gain of 2.50% over existing methods. This improvement is attributed to its ability to identify and leverage Anchor Instances, even in cases with sparse or morphologically diverse tumor regions. For pathologists, this translates to more reliable and faster diagnostic support, potentially reducing misdiagnosis rates and improving patient outcomes significantly. The framework's efficiency also allows for deployment in resource-constrained clinical settings.
