Chest X-ray images are one of the most common medical diagnosis techniques to identify different thoracic diseases. However, identification of pathologies in X-ray images requires skilled manpower and are often cited as a time-consuming task with varied level of interpretation, particularly in cases where the identification of disease only by images is difficult for human eyes. With recent achievements of deep learning in image classification, its application in disease diagnosis has been widely explored. This research project presents a multi-label disease diagnosis model of chest x-rays. Using Dense Convolutional Neural Network (DenseNet), the diagnosis system was able to obtain high classification predictions. The model obtained the highest AUC score of 0.896 for condition Cardiomegaly and the lowest AUC score for Nodule, 0.655. The model also localized the parts of the chest radiograph that indicated the presence of each pathology using GRADCAM, thus contributing to the model interpretability of a deep learning algorithm.

本项目提出了一种基于DenseNet和GRADCAM的多标签胸透疾病诊断模型，能够在X线图像中准确检测出多种胸部病理，并实现了深度学习算法的模型可解释性。
