Embedding-driven dual-branch approach for accurate breast tumor cellularity classification
Revolutionizing Breast Cancer Diagnosis with Advanced AI
This research presents a novel dual-branch AI framework for breast tumor cellularity classification from histopathological images. It integrates an Embedding Extraction Branch (embedding-driven) and a Vision Classification Branch (vision-based). The framework utilizes Virchow2 for dense embeddings and Nomic AI Embedded Vision v1.5 for visual processing. A 'Knowledge Block' with fully connected layers, batch normalization, and dropout enhances feature extraction and prevents overfitting. The model achieves 97.86% accuracy, 99.29% specificity, and 97.86% sensitivity, precision, and F1 score. Ablation studies confirm the critical role of both branches and data augmentation. This approach offers significant advancements in diagnostic consistency and interpretability for breast cancer.

Clinical Relevance & Pathologist Validation
The dual-branch architecture's medical implications are significant, offering more accurate and consistent histopathological diagnosis. By capturing high-level tumor features at low magnification and fine-grained details at high magnification, it reduces inter-observer variability. Blinded validation experiments with practicing pathologists confirmed its clinical utility and feasibility, emphasizing increased interpretability and localizability of outputs. This partnership ensures the system meets practical needs for clinicians, providing near-real-time decision support during diagnostic workflows and improving patient outcomes.
