Deep Learning Based Image Classification of Lungs Radiography for Detecting COVID-19 using a Deep CNN and ResNet 50 The first one is based on Python, where the deep neural network architecture (Inception) was built and the feature extraction part was performed. (15) can be reformulated to meet the special case of GL definition of Eq. Furthermore, using few hundreds of images to build then train Inception is considered challenging because deep neural networks need large images numbers to work efficiently and produce efficient features. The conference was held virtually due to the COVID-19 pandemic. Accordingly, that reflects on efficient usage of memory, and less resource consumption. If the random solution is less than 0.2, it converted to 0 while the random solution becomes 1 when the solutions are greater than 0.2. Objective: To help improve radiologists' efficacy of disease diagnosis in reading computed tomography (CT) images, this study aims to investigate the feasibility of applying a modified deep learning (DL) method as a new strategy to automatically segment disease-infected regions and predict disease severity.
