Stage 2 has been executed in the second third of the total number of iterations when \(\frac{1}{3}t_{max}< t< \frac{2}{3}t_{max}\). The 1360 revised papers presented in these proceedings were carefully reviewed and selected from . After feature extraction, we applied FO-MPA to select the most significant features. MPA simulates the main aim for most creatures that is searching for their foods, where a predator contiguously searches for food as well as the prey. The predator tries to catch the prey while the prey exploits the locations of its food. arXiv preprint arXiv:1704.04861 (2017). The shape of the output from the Inception is (5, 5, 2048), which represents a feature vector of size 51200. In this paper, we apply a convolutional neural network (CNN) to extract features from COVID-19 X-Ray images. Eng. Comput. Internet Explorer). Hashim, F. A., Houssein, E. H., Mabrouk, M.

In the current work, the values of k, and \(\zeta\) are set to 2, and 2, respectively. Med. Image segmentation is a necessary image processing task that applied to discriminate region of interests (ROIs) from the area of outsides. 4b, FO-MPA algorithm selected successfully fewer features than other algorithms, as it selected 130 and 86 features from Dataset 1 and Dataset 2, respectively. }\delta (1-\delta )(2-\delta ) U_{i}(t-2)\\&\quad + \frac{1}{4! 6, right), our approach still provides an overall accuracy of 99.68%, putting it first with a slight advantage over MobileNet (99.67 %). In Inception, there are different sizes scales convolutions (conv. 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 . Med. where \(ni_{j}\) is the importance of node j, while \(w_{j}\) refers to the weighted number of samples reaches the node j, also \(C_{j}\) determines the impurity value of node j. left(j) and right(j) are the child nodes from the left split and the right split on node j, respectively. However, it was clear that VGG19 and MobileNet achieved the best performance over other CNNs. In my thesis project, I developed an image classification model to detect COVID-19 on chest X-ray medical data using deep learning models such . How- individual class performance. A properly trained CNN requires a lot of data and CPU/GPU time. Currently, a new coronavirus, called COVID-19, has spread to many countries, with over two million infected people or so-called confirmed cases. 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. Chollet, F. Keras, a python deep learning library. Bisong, E. Building Machine Learning and Deep Learning Models on Google Cloud Platform (Springer, Berlin, 2019). 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. They are distributed among people, bats, mice, birds, livestock, and other animals1,2. Kong, Y., Deng, Y. The classification accuracy of MPA, WOA, SCA, and SGA are almost the same. They applied a fuzzy decision tree classifier, and they found that fuzzy PSO improved the classification accuracy. Recently, a combination between the fractional calculus tool and the meta-heuristics opens new doors in providing robust and reliable variants41. & Cmert, Z. Performance analysis of neural networks for classification of medical images with wavelets as a feature extractor. 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. With the help of numerous algorithms in AI, modern COVID-19 cases can be detected and managed in a classified framework. For each decision tree, node importance is calculated using Gini importance, Eq. Recombinant: A process in which the genomes of two SARS-CoV-2 variants (that have infected a person at the same time) combine during the viral replication process to form a new variant that is different . ), such as \(5\times 5\), \(3 \times 3\), \(1 \times 1\).

Besides, all algorithms showed the same statistical stability in STD measure, except for HHO and HGSO. New Images of Novel Coronavirus SARS-CoV-2 Now Available NIAID Now | February 13, 2020 This scanning electron microscope image shows SARS-CoV-2 (yellow)also known as 2019-nCoV, the virus that causes COVID-19isolated from a patient in the U.S., emerging from the surface of cells (blue/pink) cultured in the lab. While the second dataset, dataset 2 was collected by a team of researchers from Qatar University in Qatar and the University of Dhaka in Bangladesh along with collaborators from Pakistan and Malaysia medical doctors44. They used K-Nearest Neighbor (kNN) to classify x-ray images collected from Montgomery dataset, and it showed good performances. Duan et al.13 applied the Gaussian mixture model (GMM) to extract features from pulmonary nodules from CT images. For general case based on the FC definition, the Eq. In some cases (as exists in this work), the dataset is limited, so it is not sufficient for building & training a CNN. 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. Toaar, M., Ergen, B. IEEE Signal Process. Whereas, the slowest and the insufficient convergences were reported by both SGA and WOA in Dataset 1 and by SGA in Dataset 2. & Pouladian, M. Feature selection for contour-based tuberculosis detection from chest x-ray images. They showed that analyzing image features resulted in more information that improved medical imaging. 92, 103662. https://doi.org/10.1016/j.engappai.2020.103662 (2020). (9) as follows. (22) can be written as follows: By taking into account the early mentioned relation in Eq. 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. 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). Jcs: An explainable covid-19 diagnosis system by joint classification and segmentation. Ozturk et al. Etymology. Mutation: A mutation refers to a single change in a virus's genome (genetic code).Mutations happen frequently, but only sometimes change the characteristics of the virus. In Proceedings of the IEEE Conference on Computer Vision and Pattern Recognition, 770778 (2016). In addition, up to our knowledge, MPA has not applied to any real applications yet. where CF is the parameter that controls the step size of movement for the predator. Methods Med. For example, Da Silva et al.30 used the genetic algorithm (GA) to develop feature selection methods for ranking the quality of medical images. J. 42, 6088 (2017). Generally, the proposed FO-MPA approach showed satisfying performance in both the feature selection ratio and the classification rate. It is also noted that both datasets contain a small number of positive COVID-19 images, and up to our knowledge, there is no other sufficient available published dataset for COVID-19. In this paper, different Conv. a cough chills difficulty breathing tiredness body aches headaches a new loss of taste or smell a sore throat nausea and vomiting diarrhea Not everyone with COVID-19 develops all of these. MathSciNet The next process is to compute the performance of each solution using fitness value and determine which one is the best solution. In our example the possible classifications are covid, normal and pneumonia. 2. Chowdhury, M.E. etal. 11314, 113142S (International Society for Optics and Photonics, 2020). This task is achieved by FO-MPA which randomly generates a set of solutions, each of them represents a subset of potential features. Faramarzi et al.37 divided the agents for two halves and formulated Eqs. Deep cnns for microscopic image classification by exploiting transfer learning and feature concatenation. The test accuracy obtained for the model was 98%. In this paper, after applying Chi-square, the feature vector is minimized for both datasets from 51200 to 2000. Dual feature selection and rebalancing strategy using metaheuristic optimization algorithms in x-ray image datasets. Authors https://doi.org/10.1016/j.future.2020.03.055 (2020). 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. Future Gener. 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). Huang, P. et al. medRxiv (2020). All classication models ever, the virus mutates, and new variants emerge and dis- performed better in classifying the Non-COVID-19 images appear. Finally, the predator follows the levy flight distribution to exploit its prey location. (3), the importance of each feature is then calculated. Stage 3: This stage executed on the last third of the iteration numbers (\(t>\frac{2}{3}t_{max}\)) where based on the following formula: Eddy formation and Fish Aggregating Devices effect: Faramarzi et al.37 considered the external impacts from the environment, such as the eddy formation or Fish Aggregating Devices (FADs) effects to avoid the local optimum solutions. In this paper, each feature selection algorithm were exposed to select the produced feature vector from Inception aiming at selecting only the most relevant features.

Experimental results have shown that the proposed Fuzzy Gabor-CNN algorithm attains highest accuracy, Precision, Recall and F1-score when compared to existing feature extraction and classification techniques. They also used the SVM to classify lung CT images. Then, using an enhanced version of Marine Predators Algorithm to select only relevant features. Eng. On January 20, 2023, Japanese Prime Minister Fumio Kishida announced that the country would be downgrading the COVID-19 classification. Sci. Biomed. A survey on deep learning in medical image analysis. Da Silva, S. F., Ribeiro, M. X., Neto, Jd. In this paper, filters of size 2, besides a stride of 2 and \(2 \times 2\) as Max pool, were adopted. 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. https://doi.org/10.1155/2018/3052852 (2018). In Future of Information and Communication Conference, 604620 (Springer, 2020). Ozturk, T. et al. In this experiment, the selected features by FO-MPA were classified using KNN. 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. 111, 300323. Eq. Based on54, the later step reduces the memory requirements, and improve the efficiency of the framework. They concluded that the hybrid method outperformed original fuzzy c-means, and it had less sensitive to noises. It classifies the chest X-ray images into three categories that includes Covid-19, Pneumonia and normal. D.Y. The predator uses the Weibull distribution to improve the exploration capability. ADS (2) To extract various textural features using the GLCM algorithm. The conference was held virtually due to the COVID-19 pandemic. While, MPA, BPSO, SCA, and SGA obtained almost the same accuracy, followed by both bGWO, WOA, and SMA. arXiv preprint arXiv:2003.13145 (2020). org (2015). Liao, S. & Chung, A. C. Feature based nonrigid brain mr image registration with symmetric alpha stable filters.
