چکیده مقاله
The current paper presents Particle Swarm Optimized Wavelet Neural Network PSOWNN as a classification method for surface electromyogram sEMG pattern classification According to the literature, a change in the spectrum of surface electromyogram has largely been attributed to the change in muscle conduction velocity Therefore, such signals are used to command a robot using a WNN classifier During the experiments, the subjects are instructed by an auditory cue to elicit a contraction from the rest state and hold that finger posture for a period of 5 seconds For this purpose, two EMG electrodes attached to the human forearm are utilized to collect the EMG data Time and frequency characteristics such as Number of Zero Crossings ZC , Autoregressive AR , and wavelet coefficients are considered as features And, WNN as a classification method is optimized using particle swarm optimization algorithm The accuracy of PSOWNN is compared to that of Artificial Neural Network ANN The results show an accuracy of 90% for the proposed method, indicating a better performance than ANN in terms of accuracy Finally, outputs of the best classification method are implemented on a robot
