To improve accuracy of human hand motion pattern recognition
a pattern recognition method for optimizing support vector machine( SVM) by using artificial fish swarm algorithm( AFSA) is proposed. The maximum value of wavelet coefficients is extracted as feature samples from the de-noised surface electromyography( s EMG) signals
then the extracted feature is inputted into a SVM to classify actions recognition
and at the same time
AFSA is used to optimize the penalty parameters and the kernel parameters of the SVM
which avoids the blindness of parameters selection and improves recognition precision of the model. Simulation results show that four movements( wrist down
wrist up
hand grasps
hand extension) are successfully identified by the method of SVM combined with AFSA. Compared with the traditional SVM method
