The symbol \(R_B\) refers to Brownian motion. The predator tries to catch the prey while the prey exploits the locations of its food. HIGHLIGHTS who: Qinghua Xie and colleagues from the Te Afliated Changsha Central Hospital, Hengyang Medical School, University of South China, Changsha, Hunan, China have published the Article: Automatic Segmentation and Classification for Antinuclear Antibody Images Based on Deep Learning, in the Journal: Computational Intelligence and Neuroscience of 14/08/2022 what: Terefore, the authors . The second CNN architecture classifies the X-ray image into three classes, i.e., normal, pneumonia, and COVID-19. Currently, a new coronavirus, called COVID-19, has spread to many countries, with over two million infected people or so-called confirmed cases. However, WOA showed the worst performances in these measures; which means that if it is run in the same conditions several times, the same results will be obtained. (15) can be reformulated to meet the special case of GL definition of Eq. Inf. and M.A.A.A. 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. We can call this Task 2. 35, 1831 (2017). This algorithm is tested over a global optimization problem. Cauchemez, S. et al. Softw. & Pouladian, M. Feature selection for contour-based tuberculosis detection from chest x-ray images.

Evaluate the proposed approach by performing extensive comparisons to several state-of-art feature selection algorithms, most recent CNN architectures and most recent relevant works and existing classification methods of COVID-19 images. 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. The Softmax activation function is used for this purpose because the output should be binary (positive COVID-19 negative COVID-19). Therefore, a feature selection technique can be applied to perform this task by removing those irrelevant features. Artif. A survey on deep learning in medical image analysis. However, the proposed FO-MPA approach has an advantage in performance compared to other works. Moreover, from Table4, it can be seen that the proposed FO-MPA provides better results in terms of F-Score, as it has the highest value in datatset1 and datatset2 which are 0.9821 and 0.99079, respectively.
