For example, Lambin et al.7 proposed an efficient approach called Radiomics to extract medical image features. IEEE Signal Process. Pool layers are used mainly to reduce the inputs size, which accelerates the computation as well. Nevertheless, a common mistake in COVID-19 dataset fusion, mainly on classification tasks, is that by mixing many datasets of COVID-19 and using as Control images another dataset, there will be . Diagnosis of parkinsons disease with a hybrid feature selection algorithm based on a discrete artificial bee colony. The predator uses the Weibull distribution to improve the exploration capability. Cancer 48, 441446 (2012). To survey the hypothesis accuracy of the models. The convergence behaviour of FO-MPA was evaluated over 25 independent runs and compared to other algorithms, where the x-axis and the y-axis represent the iterations and the fitness value, respectively. As seen in Table3, on Dataset 1, the FO-MPA outperformed the other algorithms in the mean of fitness value as it achieved the smallest average fitness function value followed by SMA, HHO, HGSO, SCA, BGWO, MPA, and BPSO, respectively whereas, the SGA and WOA showed the worst results. 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. Med. }\delta (1-\delta )(2-\delta ) U_{i}(t-2)\\&\quad + \frac{1}{4! Also, As seen in Fig. For example, as our input image has the shape \(224 \times 224 \times 3\), Nasnet26 produces 487 K features, Resnet25 and Xception29 produce about 100 K features and Mobilenet27 produces 50 K features, while FO-MPA produces 130 and 86 features for both dataset1 and dataset 2, respectively. Faramarzi et al.37 divided the agents for two halves and formulated Eqs. Slider with three articles shown per slide. Credit: NIAID-RML On the second dataset, dataset 2 (Fig. Accordingly, the FC is an efficient tool for enhancing the performance of the meta-heuristic algorithms by considering the memory perspective during updating the solutions. According to the promising results of the proposed model, that combines CNN as a feature extractor and FO-MPA as a feature selector could be useful and might be successful in being applied in other image classification tasks. The largest features were selected by SMA and SGA, respectively. 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. The first one is based on Python, where the deep neural network architecture (Inception) was built and the feature extraction part was performed. kharrat and Mahmoud32proposed an FS method based on a hybrid of Simulated Annealing (SA) and GA to classify brain tumors using MRI. It also contributes to minimizing resource consumption which consequently, reduces the processing time.

My education and internships have equipped me with strong technical skills in Python, deep learning models, machine learning classification, text classification, and more. In54, AlexNet pre-trained network was used to extract deep features then applied PCA to select the best features by eliminating highly correlated features. It is calculated between each feature for all classes, as in Eq. 41, 923 (2019). The focus of this study is to evaluate and examine a set of deep learning transfer learning techniques applied to chest radiograph images for the classification of COVID-19, normal (healthy), and pneumonia. The results showed that the proposed approach showed better performances in both classification accuracy and the number of extracted features that positively affect resource consumption and storage efficiency. 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). . Then, using an enhanced version of Marine Predators Algorithm to select only relevant features. 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). Robertas Damasevicius. A. et al. The results indicate that all CNN-based architectures outperform the ViT-based architecture in the binary classification of COVID-19 using CT images. For more analysis of feature selection algorithms based on the number of selected features (S.F) and consuming time, Fig. Kharrat, A. Initialization phase: this phase devotes for providing a random set of solutions for both the prey and predator via the following formulas: where the Lower and Upper are the lower and upper boundaries in the search space, \(rand_1\) is a random vector \(\in\) the interval of (0,1). }\delta (1-\delta ) U_{i}(t-1)+ \frac{1}{3! In addition, up to our knowledge, MPA has not applied to any real applications yet. Lambin, P. et al. Initialize solutions for the prey and predator. 78, 2091320933 (2019). It also shows that FO-MPA can select the smallest subset of features, which reflects positively on performance. Besides, the binary classification between two classes of COVID-19 and normal chest X-ray is proposed. Comput.

This study presents an investigation on 16 pretrained CNNs for classification of COVID-19 using a large public database of CT scans collected from COVID-19 patients and non-COVID-19 subjects. I am passionate about leveraging the power of data to solve real-world problems. The proposed COVID-19 X-ray classification approach starts by applying a CNN (especially, a powerful architecture called Inception which pre-trained on Imagnet dataset) to extract the discriminant features from raw images (with no pre-processing or segmentation) from the dataset that contains positive and negative COVID-19 images. Therefore, several pre-trained models have won many international image classification competitions such as VGGNet24, Resnet25, Nasnet26, Mobilenet27, Inception28 and Xception29. In this subsection, the performance of the proposed COVID-19 classification approach is compared to other CNN architectures.

Moreover, the \(R_B\) parameter has been changed to depend on weibull distribution as described below. The variants of concern are Alpha, Beta, Gamma, and than the COVID-19 images. Comput. They also used the SVM to classify lung CT images. Automatic CNN-based Chest X-Ray (CXR) image classification for detecting Covid-19 attracted so much attention. It noted that all produced feature vectors by CNNs used in this paper are at least bigger by more than 300 times compared to that produced by FO-MPA in terms of the size of the featureset. For the special case of \(\delta = 1\), the definition of Eq.

(2) To extract various textural features using the GLCM algorithm. In some cases (as exists in this work), the dataset is limited, so it is not sufficient for building & training a CNN. Radiomics: extracting more information from medical images using advanced feature analysis. The family of coronaviruses is considered serious pathogens for people because they infect respiratory, hepatic, gastrointestinal, and neurologic diseases. Four measures for the proposed method and the compared algorithms are listed. The two datasets consist of X-ray COVID-19 images by international Cardiothoracic radiologist, researchers and others published on Kaggle. Vis. Litjens, G. et al. As a result, the obtained outcomes outperformed previous works in terms of the models general performance measure. The authors declare no competing interests. In the meantime, to ensure continued support, we are displaying the site without styles D.Y. Afzali, A., Mofrad, F.B. Also, all other works do not give further statistics about their models complexity and the number of featurset produced, unlike, our approach which extracts the most informative features (130 and 86 features for dataset 1 and dataset 2) that imply faster computation time and, accordingly, lower resource consumption. Chong et al.8 proposed an FS model, called Robustness-Driven FS (RDFS) to select futures from lung CT images to classify the patterns of fibrotic interstitial lung diseases. Fung, G. & Stoeckel, J.
