Summary
LExNet, a novel deep learning model, enhances breast cancer diagnosis accuracy to 98.3% using an ensemble of lightweight networks and autoencoder features. This efficient, interpretable solution aids real-time diagnostics, especially in resource-limited settings.
Area of Science:
- * Medical image analysis
- * Computational pathology
- * Artificial intelligence in oncology
Background:
- * Breast cancer diagnosis relies on histopathology, which is labor-intensive and prone to variability.
- * Accurate and timely diagnosis is crucial for effective breast cancer treatment.
- * Existing methods face challenges in efficiency and consistency.
Purpose of the Study:
- * To introduce LExNet, a bio-inspired lightweight ensemble model for breast cancer diagnosis.
- * To improve diagnostic accuracy and computational efficiency in histopathological image analysis.
- * To provide an interpretable and robust solution for real-time breast cancer detection.
Main Methods:
- * Development of LExNet, an ensemble of lightweight Convolutional Neural Network (CNN) architectures (MobileNetV3, EfficientNet-B0, ShuffleNet-V2, SqueezeNet).
- * Integration of hybrid autoencoder-based feature extraction for noise and dimensionality reduction.
- * Application of Particle Swarm Optimization (PSO) for efficient hyperparameter tuning.
- * Utilization of Grad-CAM for model interpretability analysis.
Main Results:
- * LExNet achieved a validation accuracy of approximately 98.3% on the ICIAR 2018 BACH dataset.
- * Demonstrated a 40-50% reduction in computational demands compared to traditional models.
- * Reduced overfitting risk by over 30% through autoencoder feature extraction.
- * Decreased manual hyperparameter tuning time by up to 70% using PSO.
- * Grad-CAM analysis confirmed alignment of predictions with expert pathologist insights.
Conclusions:
- * LExNet offers a highly accurate and computationally efficient solution for breast cancer diagnosis.
- * The model's interpretability enhances clinical relevance and trust.
- * LExNet is particularly suitable for resource-constrained clinical settings, enabling real-time diagnostics.
