Abstract: In order to build an interpretable AI model to realize rapid and accurate diagnosis of COVID-19, this paper uses the Python programming language and Pytorch deep learning framework to build CNN and DenseNet models based on the image classification technology of deep learning algorithm and through the preprocessing and data enhancement of chest X-ray data sets. The automatic diagnosis of lung diseases is realized, and the performance of the two models is evaluated and compared. The results show that the DenseNet model performs better in image classification task, has better clas-sification accuracy and faster convergence rate. This study provides a new idea and method for the research in the field of medical image recognition and has certain application value for improving the accuracy and efficiency of medical diagnosis.
