Fig 6 shows the performances of different approaches using accuracy, specificity, sensitivity and error rate parameters in a graphical manner. It is observed that PSO-ANN approached obtains higher accuracy, sensitivity, specificity rate and low error rate for dengue disease. While, DT approach shows poor performance among all other approaches. It is stated that significant differences occur between the performances of the above mentioned approaches and concluded that PSO-ANN based diagnostic model is more capable to detect and diagnosis of dengue disease in earlier stage. Based on the experimental study, the following point can be highlighted.
