From: Gesture recognition method based on a single-channel sEMG envelope signal
Comparison of accuracy of recognition for three algorithms. a Accuracy in 14-dimensional feature space. b Accuracy in 2-dimensional feature space. The legends first, second, third, fourth, fifth, and mean, respectively, represent the first gesture, the second gesture, the third gesture, the fourth gesture, the fifth gesture, and mean of five types of gestures. T-KNN represents the traditional KNN algorithm, and I-KNN represents the improved KNN algorithm. S-SVM represents the soft margin SVM algorithm
