Rapid energy expenditure estimation for ankle assisted and inclined loaded walking

Table 3 Average error for models with input features of either ground reaction forces or EMG signals when estimating energy expenditure during all conditions in the dataset for a new subject

Dataset	Model	Forces^a	EMG^b
Assisted	Linear Regression	8.7%	9.4%
	Neural Network	8.1%	9.2%
Incline-load	Linear Regression	12.5%	31.6%
	Neural Network	11.5%	23.9%

^aThe model’s input features were restricted to only include the ground reaction forces, excluding the EMG signals
^bThe model’s input features were restricted to only include the EMG signals, excluding the ground reaction forces
