Before revision:  These aspects challenge the assessment of functionally relevant features which are of special importance in closed-loop applications as ,  e.g., in the field of rehabilitation.
After revision:  These aspects challenge the assessment of functionally relevant features which are of special importance in closed-loop applications as , however, disregard within-trial temporal dynamics and are extremely sensitive to changes in training data and involved hyperparameters. This leads to highly variable solutions and impedes the selection of a suitable candidate for, e.g., in the field of rehabilitation.
