The whole dataset contains around 200 COVID-19 positive images and 1675 negative COVID19 images. & Cmert, Z. Hence, it was discovered that the VGG-16 based DTL model classified COVID-19 better than the VGG-19 based DTL model. arXiv preprint arXiv:2003.13145 (2020). However, the proposed FO-MPA approach has an advantage in performance compared to other works. Inspired by our recent work38, where VGG-19 besides statistically enhanced Salp Swarm Algorithm was applied to select the best features for White Blood Cell Leukaemia classification. In general, MPA is a meta-heuristic technique that simulates the behavior of the prey and predator in nature37. the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in Comparison with other previous works using accuracy measure. & Cmert, Z. The classification accuracy of MPA, WOA, SCA, and SGA are almost the same. Although convolutional neural networks (CNNs) is considered the current state-of-the-art image classification technique, it needs massive computational cost for deployment and training. Hence, the FC memory is applied during updating the prey locating in the second step of the algorithm to enhance the exploitation stage. Appl. The proposed IMF approach successfully achieves two important targets, selecting small feature numbers with high accuracy. So, there might be sometimes some conflict issues regarding the features vector file types or issues related to storage capacity and file transferring. It achieves a Dice score of 0.9923 for segmentation, and classification accuracies of 0. For the special case of \(\delta = 1\), the definition of Eq. Whereas the worst one was SMA algorithm. The Weibull Distribution is a heavy-tied distribution which presented as in Fig. Med.

Article Key Definitions. The model was developed using Keras library47 with Tensorflow backend48. Authors For Dataset 2, FO-MPA showed acceptable (not the best) performance, as it achieved slightly similar results to the first and second ranked algorithm (i.e., MPA and SMA) on mean, best, max, and STD measures. (18)(19) for the second half (predator) as represented below. 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. 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. The announcement confirmed that from May 8, following Japan's Golden Week holiday period, COVID-19 will be officially downgraded to Class 5, putting the virus on the same classification level as seasonal influenza.
