Fractional-order calculus (FC) gains the interest of many researchers in different fields not only in the modeling sectors but also in developing the optimization algorithms. CAS Objective: Lung image classification-assisted diagnosis has a large application market. Therefore, reducing the size of the feature from about 51 K as extracted by deep neural networks (Inception) to be 128.5 and 86 in dataset 1 and dataset 2, respectively, after applying FO-MPA algorithm while increasing the general performance can be considered as a good achievement as a machine learning goal.

Li, S., Chen, H., Wang, M., Heidari, A. For each of these three categories, there is a number of patients and for each of them, there is a number of CT scan images correspondingly. In14, the authors proposed an FS method based on a convolutional neural network (CNN) to detect pneumonia from lung X-ray images. Radiomics: extracting more information from medical images using advanced feature analysis. Support Syst. 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. J. Med. Therefore, in this paper, we propose a hybrid classification approach of COVID-19. It also contributes to minimizing resource consumption which consequently, reduces the processing time. In this paper, we proposed a novel COVID-19 X-ray classification approach, which combines a CNN as a sufficient tool to extract features from COVID-19 X-ray images.

Correspondence to Coronavirus disease (Covid-19) is an infectious disease that attacks the respiratory area caused by the severe acute . IEEE Trans. & Mahmoud, N. Feature selection based on hybrid optimization for magnetic resonance imaging brain tumor classification and segmentation. Meanwhile, the prey moves effectively based on its memory for the previous events to catch its food, as presented in Eq. 2020-09-21 . Tree based classifier are the most popular method to calculate feature importance to improve the classification since they have high accuracy, robustness, and simple38. It is obvious that such a combination between deep features and a feature selection algorithm can be efficient in several image classification tasks. However, the proposed FO-MPA approach has an advantage in performance compared to other works. 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. Harikumar et al.18 proposed an FS method based on wavelets to classify normality or abnormality of different types of medical images, such as CT, MRI, ultrasound, and mammographic images. To obtain Med. As seen in Table1, we keep the last concatenation layer which contains the extracted features, so we removed the top layers such as the Flatten, Drop out and the Dense layers which the later performs classification (named as FC layer). In this paper, filters of size 2, besides a stride of 2 and \(2 \times 2\) as Max pool, were adopted. Thereafter, the FO-MPA parameters are applied to update the solutions of the current population. 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. Slider with three articles shown per slide. For diagnosing COVID-19, the RT-PCR (real-time polymerase chain reaction) is a standard diagnostic test, but, it can be considered as a time-consuming test, more so, it also suffers from false negative diagnosing4. & Dai, Q. Discriminative clustering and feature selection for brain mri segmentation. J. Also, other recent published works39, who combined a CNN architecture with Weighted Symmetric Uncertainty (WSU) to select optimal features for traffic classification. This dataset currently contains hundreds of frontal view X-rays and is the largest public resource for COVID-19 image and prognostic data, making it a necessary resource to develop and evaluate tools to aid in the treatment of CO VID-19.
