Normal breast tissue (NBT)-classifiers: advancing compartment classification in normal breast histology
This paper introduces NBT-Classifiers, a new AI-powered computational pathology tool designed for detailed analysis of normal breast tissue histology. By leveraging robust convolutional neural networks (CNNs) trained on a diverse dataset of whole slide images (WSIs), NBT-Classifiers accurately classify epithelium, stroma, and adipocytes at various scales. This tool significantly enhances the understanding of NBT appearances, providing valuable reference points for identifying premalignant changes and guiding early breast cancer prevention strategies.

Robust Classification Performance
The NBT-Classifiers demonstrated exceptional accuracy across diverse external cohorts, showcasing strong generalizability crucial for real-world application in clinical and research settings. Our models, particularly the 512px and 1024px versions, achieved near-perfect AUCs for classifying key breast tissue compartments.
Peak AUC for Adipocyte Classification across all cohorts.
Distinctive Normal-Specific Feature Learning
Unlike models trained on mixed tissue types, NBT-Classifiers were specifically trained on normal breast tissue. This specialized training enabled the models to learn unique architectural features characteristic of normal tissue, distinguishing them effectively from abnormal or cancerous epithelial patterns. This capability is vital for early detection and precision diagnostics.

End-to-End WSI Pre-processing Pipeline
To maximize utility, NBT-Classifiers are integrated into a comprehensive WSI pre-processing pipeline. This pipeline automates the detection of foreground tissue, classification into compartments, and identification of critical regions like lobules. This streamlined process facilitates advanced downstream analyses, such as multi-instance learning, by ensuring consistent and objective patch selection.
