To address this challenge, this paper proposes a two-path semi- supervised deep learning model, ssResNet, based on Residual Neural Network (ResNet) for COVID-19 image classification, where two paths refer to a supervised path and an unsupervised path, respectively. Therefore in MPA, for the first third of the total iterations, i.e., \(\frac{1}{3}t_{max}\)). The largest features were selected by SMA and SGA, respectively. In Future of Information and Communication Conference, 604620 (Springer, 2020). Int. 4 and Table4 list these results for all algorithms. The announcement confirmed that from May 8, following Japan's Golden Week holiday period, COVID-19 will be officially downgraded to Class 5, putting the virus on the same classification level as seasonal influenza. CNNs are more appropriate for large datasets. Szegedy, C. et al.

As Inception examines all X-ray images over and over again in each epoch during the training, these rapid ups and downs are slowly minimized in the later part of the training. Initialize solutions for the prey and predator. Med. Since its structure consists of some parallel paths, all the paths use padding of 1 pixel to preserve the same height & width for the inputs and the outputs. Currently, we witness the severe spread of the pandemic of the new Corona virus, COVID-19, which causes dangerous symptoms to humans and animals, its complications may lead to death.

Faramarzi et al.37 implement this feature via saving the previous best solutions of a prior iteration, and compared with the current ones; the solutions are modified based on the best one during the comparison stage. Based on Standard Deviation measure (STD), the most stable algorithms were SCA, SGA, BPSO, and bGWO, respectively. In Table4, for Dataset 1, the proposed FO-MPA approach achieved the highest accuracy in the best and mean measures, as it reached 98.7%, and 97.2% of correctly classified samples, respectively. The MPA starts with the initialization phase and then passing by other three phases with respect to the rational velocity among the prey and the predator. Although outbreaks of SARS and MERS had confirmed human to human transmission3, they had not the same spread speed and infection power of the new coronavirus (COVID-19). Both the model uses Lungs CT Scan images to classify the covid-19. In such a case, in order to get the advantage of the power of CNN and also, transfer learning can be applied to minimize the computational costs21,22. Nature 503, 535538 (2013). Google Scholar. A properly trained CNN requires a lot of data and CPU/GPU time. Whereas, the worst algorithm was BPSO. This algorithm is tested over a global optimization problem.
