Enhanced Chest Disease Classification Using an Improved CheXNet Framework with EfficientNetV2-M and Optimization-Driven Learning
Published on 2024-07-25 by Ali M. Bahram et al.
Executive Impact Summary
This research presents a novel framework for chest X-ray classification, significantly outperforming the baseline CheXNet (DenseNet-121) by integrating EfficientNetV2-M with advanced optimization techniques. The system achieves superior diagnostic accuracy (96.45%), enhanced F1-score (91.08%), and improved training efficiency and stability. Notably, it delivers near-perfect classification for critical infectious diseases like COVID-19 (99.95% accuracy) and Tuberculosis (99.97% accuracy). The framework is robust, reproducible, and suitable for clinical deployment in various healthcare settings, especially in resource-limited environments, serving as a powerful decision-support tool for pandemic response and disease screening.
