The entire dataset comes from Kermany et al. on Mendeley, although there is also a version on Kaggle that may be easier to use. This task is to: Build a model that can classify whether a given patient has pneumonia, given a chest x-ray image. To speed up image pre-processing, ...
To diagnose Coronavirus from X-ray Image dataset using different Convolutional Neural Network methodologies like Mobile Net, Inception, Exception, VGG. However, the findings obtained are based on the VGG16, VGG19 model. Apply the models to the X-ray dataset this was obtained from the Kaggle ...
