Figure 1.1 Methodology.

1.4 Results and Discussion

This work uses Orange 3-3.24.1 [56] for the simulation purpose. Several TEMVIs with different sizes are taken from the source [59–88]. In this work, 30 TEMVIs with 6 images of each category such as EV, ENV, LV, SARS-CoV-2 and ZV are taken for testing purpose which is mentioned in Figures 1.2–1.6. The TEMVIs are processed using ML-based classification techniques such as LR, NN, kNN and NB. The classification results of these techniques are mentioned in Figures 1.7–1.10, 1.11–1.14, 1.15–1.18, 1.19–1.22, 1.23–1.26 by considering number of folds (NoF) as 2, 3, 5, 10 and 20 respectively. In this work, five different cases such as cases-I–V are considered by taking five different NoF such as 2, 3, 5, 10 and 20 respectively.

      Figure 1.4 Lassa virus images (1–6) with sizes 251 × 201, 180 × 180, 259 × 194, 241 × 209, 262 × 192, 299 × 168 respectively.

Figure 1.5 SARS-CoV-2 virus images (1–6) with sizes 225 × 225, 256 × 197, 254 × 198, 243 × 207, 249 × 203, 300 × 168 respectively.

The test and score calculation is carried out by using cross validation sampling mechanism with different NoF. The classification results generated by using confusion matrix for each of these classification techniques represent actual and predicted values by showing the number of instances. The correct classification results are represented by the help of light blue color and the misclassification results are represented by the help of light red color. Table 1.1 represents the CA values by applying the LR, NN, kNN and NB classification techniques.
