“…Our research group has previously approximated spectral analysis of EMG signals and extracted features using reflection coefficients [15] and classified the results with SVM, without any feature reduction. It is shown in [16] that discrete wavelet transform followed by principal component analysis (PCA) and SVM could enhance the accuracy of classifications. Several other EMG classifiers have been applied using decision trees [17], random forest [18], KNN [14], [19], Naïve Bayes classifier [20], and SVM [15], [17], [21].…”
