In ancient India, according to Aelian, it was . 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. Article Sci. This dataset consists of 219 COVID-19 positive images and 1341 negative COVID-19 images. They are distributed among people, bats, mice, birds, livestock, and other animals1,2. Table3 shows the numerical results of the feature selection phase for both datasets. The second CNN architecture classifies the X-ray image into three classes, i.e., normal, pneumonia, and COVID-19.

The definitions of these measures are as follows: where TP (true positives) refers to the positive COVID-19 images that were correctly labeled by the classifier, while TN (true negatives) is the negative COVID-19 images that were correctly labeled by the classifier. International Conference on Machine Learning647655 (2014). 6, right), our approach still provides an overall accuracy of 99.68%, putting it first with a slight advantage over MobileNet (99.67 %). Lung Cancer Classification Model Using Convolution Neural Network Furthermore, the proposed GRAY+GRAY_HE+GRAY_CLAHE image representation was evaluated on two different datasets, SARS-CoV-2 CT-Scan and New_Data_CoV2, where it was found to be superior to RGB . Accordingly, the prey position is upgraded based the following equations. Although the performance of the MPA and bGWO was slightly similar, the performance of SGA and WOA were the worst in both max and min measures. TOKYO, Jan 26 (Reuters) - Japan is set to downgrade its classification of COVID-19 to that of a less serious disease on May 8, revising its measures against the coronavirus such as relaxing.
