Detection and Classification of Pneumonia Using Explainable AI

Pneumonia continues to pose a significant public health threat, particularly among vulnerable populations such as children, the elderly, and individuals with compromised immune systems. Early and accurate diagnosis is critical for effective treatment and the prevention of severe complications. While chest X-rays are a standard diagnostic tool, their interpretation is often subjective and reliant on the expertise of radiologists, leading to potential delays and inconsistencies. To address these challenges, this study presents a deep learning-based model augmented with explainable artificial intelligence (XAI) for the automated detection of pneumonia in chest radiographs. The proposed system integrates interpretability techniques—Grad-CAM, LIME, and SHAP—to provide visual explanations of the model’s decision-making process. By highlighting the specific regions of interest that contribute to the diagnosis, the system enhances transparency, fosters trust among medical professionals, and supports clinical decision-making. The model achieved high accuracy in detecting pneumonia and demonstrated practical utility in clinical settings, offering a reliable and interpretable solution to improve diagnostic workflows.
