“…Model is simply trying to get down to the minimum error loss, node by node, until the final outcome with the maximum reduction of loss has reached. Weights are adjustable depending on the metric chosen [26].This method works well for data such as variable as Covid-19 data, but another crucial part is dividing the data for training.We need to have enough historical data for the model to train well which results in more accurate prediction or test trials.Part of the data is classified as training data and the rest is classified as testing, with a 70:30 training validation split.Here is where we need to look at some of the most relevant parameters of the model which are: learning rate, number of leaves, and the maximum depth. The loss function graph and the number of iterations are being observed when adjusting these parameters [27].…”

“…For the data analysis, it is inevitable to check whether the data is seasonal or not and whether there is any autocorrelation, in order to get a better sense of choosing the parameters for the model [24].In [25][26][27][28][29] provided the segmentation of the CXR images in diagnosis of COVID-19 in Chest X-ray images. As seen in [Figure 3] the data was quite seasonal from October to July, and the it lowers, and it goes back up in the following October.…”

“…We compared our proposed model to various methods, as shown in Table 12 . The comparison shows the proposed model, EVAE-Net, outperformed the methods in [ 37 , 40 , 41 , 95 , 96 ] using the same dataset (COVID-19 Radiography Database) for COVID-19 classification and methods that used other modalities [ 17 , 38 , 49 , 97 ]. It was worth noting that most of these methods only focused on either three classes or four classes.…”

“…The goal of this is to improve the image quality of CXR scans, as well as to detect and diagnose medical conditions at an affordable cost. In [16,17], authors implemented segmentation and classification based approaches to detect COVID-19 from the chest X-ray images. In today's world, methods using artificial intelligence such as machine learning [18] and deep learning [19] are beginning to show prospective outcomes in the analysis of medical pictures.…”

“…Figure 7 presents a graphical representation of the loss function for both the learning dataset and the validation dataset (a). In this example, the loss values for the learning dataset are obtained to be 0.051 and 0.044, In this context, SVM [17], KNN [15], and RF [18]are examples of current techniques. The effectiveness of the proposed methodology is compared to the efficacy of these existing approaches in Table 2.…”
