“…In contrast to physics-based approaches, machine learning models require representative training data. Combining simulated and measured data seems a promising approach (Mundt et al, 2020a ). In this work, we focused on the comparison between learning on measured and learning on simulated data to evaluate whether simulations can decrease the generalization error by incorporating variations of movement.…”

“…In this work, we focused on the comparison between learning on measured and learning on simulated data to evaluate whether simulations can decrease the generalization error by incorporating variations of movement. Future work should expand this method to 3D analysis and evaluate against state of the art methods (Stetter et al, 2019 ; Mundt et al, 2020a ). 3D biomechanical optimal control simulations are more expensive to compute, but are advancing recently (Falisse et al, 2019 ).…”

“…For the functional calibration, the user needs to be able to execute the required position of movement. Expert knowledge is necessary for both methods to ensure a meaningful and repeatable calibration [ 8 , 12 ]. Lebleu et al [ 8 ] achieved mean RMSE values for functional calibrations of 2.0 to 4.1°.…”
