Future Gener. This means we can use pre-trained model weights, leveraging all of the time and data it took for training the convolutional part, and just remove the FCN layer. We adopt a special type of CNN called a pre-trained model where the network is previously trained on the ImageNet dataset, which contains millions of variety of images (animal, plants, transports, objects,..) on 1000 classe categories. The code of the proposed approach is also available via the following link [https://drive.google.com/file/d/1-oK-eeEgdCMCnykH364IkAK3opmqa9Rvasx/view?usp=sharing]. 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. 101, 646667 (2019). \(\bigotimes\) indicates the process of element-wise multiplications.

The next process is to compute the performance of each solution using fitness value and determine which one is the best solution. Harikumar et al.18 proposed an FS method based on wavelets to classify normality or abnormality of different types of medical images, such as CT, MRI, ultrasound, and mammographic images.

Early diagnosis, timely treatment, and proper confinement of the infected patients are some possible ways to control the spreading of . More so, a combination of partial differential equations and deep learning was applied for medical image classification by10. \(Fit_i\) denotes a fitness function value. It also contributes to minimizing resource consumption which consequently, reduces the processing time. 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. So, transfer learning is applied by transferring weights that were already learned and reserved into the structure of the pre-trained model, such as Inception, in this paper. As a result, the obtained outcomes outperformed previous works in terms of the models general performance measure. The first one is based on Python, where the deep neural network architecture (Inception) was built and the feature extraction part was performed. For the special case of \(\delta = 1\), the definition of Eq. Meanwhile, the prey moves effectively based on its memory for the previous events to catch its food, as presented in Eq. In such a case, in order to get the advantage of the power of CNN and also, transfer learning can be applied to minimize the computational costs21,22. IEEE Trans.

Thereafter, the FO-MPA parameters are applied to update the solutions of the current population. & Cao, J. Cauchemez, S. et al. For the exploration stage, the weibull distribution has been applied rather than Brownian to bost the performance of the predator in stage 2 and the prey velocity in stage 1 based on the following formula: Where k, and \(\zeta\) are the scale and shape parameters. 115, 256269 (2011). Automated detection of covid-19 cases using deep neural networks with x-ray images. They applied a fuzzy decision tree classifier, and they found that fuzzy PSO improved the classification accuracy. However, WOA showed the worst performances in these measures; which means that if it is run in the same conditions several times, the same results will be obtained. I am passionate about leveraging the power of data to solve real-world problems. 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 . 22, 573577 (2014).
