diagnosed through manual interpretation of chest X rays by expert radiologists which can be costly and time consuming An alternative approach involves leveraging automated systems to identify pneumonia from chest X ray images offering a more economical and accessible solution The dataset obtained from Kaggle serves as a valuable resource for developing and testing automated pneumonia identification systems Using pre trained Convolutional Neural Network CNN models these systems analyze image features and patterns enabling efficient pneumonia detection without the need for specialized expertise This automated approach facilitates early detection of pneumonia allowing for prompt initiation of treatment during the early stages of the disease By reducing reliance on expert radiologists this method not only increases accessibility to diagnosis but also aids physicians in confirming pneumonia diagnoses swiftly and accurately Early detection is critical in enabling timely medical interventions which can significantly improve patient outcomes by preventing disease progression and complications By streamlining the diagnostic process and empowering healthcare providers with automated tools this approach contributes to more effective management of pneumonia cases ultimately leading to better patient care and outcomes KEYWORDS Pneumonia Chest X ray Automated systems
