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 survey asked participants to broadly classify the findings of each chest CT into one of the four RSNA COVID-19 imaging categories, then select which imaging features led to their categorization. Extensive comparisons had been implemented to compare the FO-MPA with several feature selection algorithms, including SMA, HHO, HGSO, WOA, SCA, bGWO, SGA, BPSO, besides the classic MPA. 121, 103792 (2020). The given Kaggle dataset consists of chest CT scan images of patients suffering from the novel COVID-19, other pulmonary disorders, and those of healthy patients. The proposed IMF approach successfully achieves two important targets, selecting small feature numbers with high accuracy. Four measures for the proposed method and the compared algorithms are listed. After feature extraction, we applied FO-MPA to select the most significant features. (4). More so, a combination of partial differential equations and deep learning was applied for medical image classification by10. Can ai help in screening viral and covid-19 pneumonia? For example, Lambin et al.7 proposed an efficient approach called Radiomics to extract medical image features. This stage can be mathematically implemented as below: In Eq. With the help of numerous algorithms in AI, modern COVID-19 cases can be detected and managed in a classified framework. Automatic CNN-based Chest X-Ray (CXR) image classification for detecting Covid-19 attracted so much attention. In addition, up to our knowledge, MPA has not applied to any real applications yet. & Mirjalili, S. Slime mould algorithm: A new method for stochastic optimization.

In Dataset 2, FO-MPA also is reported as the highest classification accuracy with the best and mean measures followed by the BPSO. arXiv preprint arXiv:1409.1556 (2014). ADS Howard, A.G. etal. J. Clin. 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. The prey follows Weibull distribution during discovering the search space to detect potential locations of its food. COVID-19 Chest X -Ray Image Classification with Neural Network It based on using a deep convolutional neural network (Inception) for extracting features from COVID-19 images, then filtering the resulting features using Marine Predators Algorithm (MPA), enhanced by fractional-order calculus(FO). Design incremental data augmentation strategy for COVID-19 CT data. Inspired by this concept, Faramarzi et al.37 developed the MPA algorithm by considering both of a predator a prey as solutions. Types of coronavirus, their symptoms, and treatment - Medical News Today Johnson et al.31 applied the flower pollination algorithm (FPA) to select features from CT images of the lung, to detect lung cancers. The results show that, using only 6 epochs for training, the CNNs achieved very high performance on the classification task.

Meanwhile, the prey moves effectively based on its memory for the previous events to catch its food, as presented in Eq. Radiology 295, 2223 (2020). & Dai, Q. Discriminative clustering and feature selection for brain mri segmentation. Moreover, the \(R_B\) parameter has been changed to depend on weibull distribution as described below. The proposed cascaded system is proposed to segment the lung, detect, localize, and quantify COVID-19 infections from computed tomography images, which can reliably localize infections of various shapes and sizes, especially small infection regions, which are rarely considered in recent studies.

Japan to downgrade coronavirus classification on May 8 - NHK Decaf: A deep convolutional activation feature for generic visual recognition. COVID-19 tests are currently hard to come by there are simply not enough of them and they cannot be manufactured fast enough, which is causing panic. Classification of COVID-19 X-ray images with Keras and its - Medium Afzali et al.15 proposed an FS method based on principal component analysis and contour-based shape descriptors to detect Tuberculosis from lung X-Ray Images. One of the drawbacks of pre-trained models, such as Inception, is that its architecture required large memory requirements as well as storage capacity (92 M.B), which makes deployment exhausting and a tiresome task. In addition, the good results achieved by the FO-MPA against other algorithms can be seen as an advantage of FO-MPA, where a balancing between exploration and exploitation stages and escaping from local optima were achieved. Marine memory: This is the main feature of the marine predators and it helps in catching the optimal solution very fast and avoid local solutions. 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. In Smart Intelligent Computing and Applications, 305313 (Springer, 2019). However, it has some limitations that affect its quality. CAS The proposed IFM approach is summarized as follows: Extracting deep features from Inception, where about 51 K features were extracted. PubMed (8) can be remodeled as below: where \(D^1[x(t)]\) represents the difference between the two followed events. In this paper, different Conv.
