The F1-score is the harmonic mean of precision and recall. Below equation used to calculate the F1-score.

Figure 2.6 shows the F1-score 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 2.5 shows the F1-Score comparison between the model-1 and model-2.

Table 2.5 F1-score of the model.

Health status	Model 1	Model 2
F1-score:Phase-I	F1-score:Phase-II	F1-score:Phase-I	F1-score:Phase-II
Sleep	94.50549	96.25668	95.08197	96.84211
Smoke	95.69892	96.84211	96.84211	97.89474
