Machine learning and machine learned prediction in chest X-ray images

Jul 31, 2025

This study addresses binary classification of thoracic diseases from chest X-ray images, leveraging a clinical dataset of 5,824 images. Method: We systematically compare a baseline CNN against DenseNet-121, fine-tuning the latter via transfer learning and integrating Grad-CAM for lesion localization and enhanced decision interpretability. Results: DenseNet-121 significantly outperforms the baseline—achieving a 3.2% higher accuracy and a 0.042 improvement in AUC. Its dense connectivity enables more effective capture of localized pathological features, yielding superior localization precision in pulmonary abnormal regions and greater classification robustness. This work validates DenseNet-121’s efficacy in medical imaging tasks with limited training data and, through rigorous interpretability analysis, provides clinically credible, human-interpretable decision support for AI-assisted diagnosis.
