Table 3

Percentage of correct classifications of each class considering oxygen saturation case library.

Sessions	Using only time domain features; (TmF)	Using only frequency domain features; (FrqF)	Using only time-frequency domain features; (TmFrqF)	Using a combination of features; TmF = 10%,; TmFrqF = 10%, and FrqF = 80%
Baseline	31.0%	100.0%	27.5%	100.0%
Deep breath	24.1%	65.5%	34.5%	72.0%
Activity	62.0%	100%	51.1%	100.0%
Relax	27.6%	38.0%	24.7%	48.0%
Average	36.2%	76.0%	34.5%	80.0%

TmF: time domain features, FrqF: frequency domain features, and TmFrqF: time-frequency domain features.
