Software available from tensorflow. Stage 2: The prey/predator in this stage begin exploiting the best location that detects for their foods. Design incremental data augmentation strategy for COVID-19 CT data. Therefore, in this paper, we propose a hybrid classification approach of COVID-19. Image segmentation is a necessary image processing task that applied to discriminate region of interests (ROIs) from the area of outsides. (23), the general formulation for the solutions of FO-MPA based on FC memory perspective can be written as follows: After checking the previous formula, it can be detected that the motion of the prey becomes based on some terms from the previous solutions with a length of (m), as depicted in Fig. Support Syst. The proposed IMF approach successfully achieves two important targets, selecting small feature numbers with high accuracy. Using the best performing fine-tuned VGG-16 DTL model, tests were carried out on 470 unlabeled image dataset, which was not used in the model training and validation processes. 111, 300323. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article.

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. (9) as follows. 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. However, the modern name is tenggiling.In Javanese it is terenggiling; and in the Philippine languages, it is goling, tanggiling, or balintong (with the same meaning).. Tree based classifier are the most popular method to calculate feature importance to improve the classification since they have high accuracy, robustness, and simple38.

They were manually aggregated from various web based repositories into a machine learning (ML) friendly format with accompanying data loader code. Correspondence to Hence, the FC memory is applied during updating the prey locating in the second step of the algorithm to enhance the exploitation stage. Therefore, several pre-trained models have won many international image classification competitions such as VGGNet24, Resnet25, Nasnet26, Mobilenet27, Inception28 and Xception29. 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. Compared to59 which is one of the most recent published works on X-ray COVID-19, a combination between You Only Look Once (YOLO) which is basically a real time object detection system and DarkNet as a classifier was proposed. Also, in12, an Fs method based on SVM was proposed to detect Alzheimers disease from SPECT images. 2. Detecting COVID-19 at an early stage is essential to reduce the mortality risk of the patients. The following stage was to apply Delta variants. The combination of SA and GA showed better performances than the original SA and GA. Narayanan et al.33 proposed a fuzzy particle swarm optimization (PSO) as an FS method to enhance the classification of CT images of emphysema. Thereafter, the FO-MPA parameters are applied to update the solutions of the current population. 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). 6, right), our approach still provides an overall accuracy of 99.68%, putting it first with a slight advantage over MobileNet (99.67 %). Whereas the worst one was SMA algorithm. They are distributed among people, bats, mice, birds, livestock, and other animals1,2. Ozturk et al.

CAS In this paper, we try to integrate deep transfer-learning-based methods, along with a convolutional block attention module (CBAM), to focus on the relevant portion of the feature maps to conduct an image-based classification of human monkeypox disease. For this motivation, we utilize the FC concept with the MPA algorithm to boost the second step of the standard version of the algorithm. For more analysis of feature selection algorithms based on the number of selected features (S.F) and consuming time, 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. This stage can be mathematically implemented as below: In Eq. In ancient India, according to Aelian, it was . These images have been further used for the classification of COVID-19 and non-COVID-19 images using ResNet50 and AlexNet convolutional neural network (CNN) models.
