An example of the importance coefficient distribution of the raw EMG features using the MRF method. β and γ are two parameters used in the MRF feature selection criterion [19]. β is a constant factor related to the number of selected features from the high dimensional feature vectors. γ is a free parameter. Both β and γ were set the same values as suggested in [19].
