The developed web app can help the users upload their own images and give the prediction results. Our SCNN model is promising in diagnosing COVID-19. It performs better than ten state-of-the-art COVID-19 diagnosis methods. The SCNN model performs better than the ReLU-based backbone network and LReLU-based backbone network, indicating the effectiveness of the Swish function. A web app is developed based on the proposed SCNN model. Our model is named Swish-based CNN (SCNN).

The multiple-way data augmentation is utilized to enhance the training set. Then, we utilize the Swish activation function to replace traditional ReLU. We first propose a 12-layer CNN-based backbone network. CT-based diagnosis methods need special expert knowledge, and the labeling procedure is tedious. COVID-19 has triggered 6.42 million death tolls, and more than 586 million confirmed positive cases until 10/Aug/2022.
