Table 10 Mean absolute percentage error compared with other algorithms

Author	Algorithm	Refs.	Number of features	Activity	MAPE [%]
Proposed	Classification tree Multi-regression model		2	6 different walks, jogging, stair	13.9
Mitja Luštrek	REPTree	[11]	8 (accelerometer)	Running	12.6^a
Hristija Gjoreski	Random forest Multiple Contexts Ensemble	[12]	128 (accelerometer)	Walk, running	15.7

^aThis value was calculated as the MAPE to the mean value of METs at two different speeds
