Figure 2.3 Accuracy: Model-I vs Model-II.
2.5.1.2 Precision
The precision of the model is calculated using the equation given below.
Figure 2.4 shows the precision comparison between the two models which are proposed in this chapter and it is observed the model-II gives more accuracy than the model-I. Table 2.3 shows the Precision comparison between the model-1 and model-2.
2.5.1.3 Recall
The recall of the model is calculated using the equation given below.
