Abstract - The issue of pneumonia remains a topic of concern globally, and con-sequently, proper diagnosis is extremely critical to improving the prognosis of patients suffering from it. This work evaluates the use of deep learning models, ResNet-50, EfficientNet, and MobileNet, for the class of pneumonia from chest X-ray images. We employed a dataset of about 8,000 images and performed ex-periments to determine the extent to which model performance depended on data augmentation and the chosen network architecture. The experimental results showed that MobileNet achieved the highest accuracy (97.51%) without the use of augmentations, whereas EfficientNet attained peak accuracy (97.12%) with the use of augmentations. Furthermore, we applied Gradient-Weighted Class Ac-tivation Maps, which added value to the model’s ability to be understood by the users. The results showed that with the aid of Explainable Artificial Intelligence (XAI) techniques, deep learning automation of pneumonia detection holds great promise. Further work should be conducted on multi-class classification and ex-ternal validation, and it is generally more useful to employ sophisticated means of explanation to ensure the model is more useful and reliable in a clinical setting.
