Abstract :
It is very important for the development of prosthesis to improve the technique of automatic pattern recognition of EMG signals. The conventional means have the disadvantage of slow training speed and limitation in problem scale. This paper proposes a new method which adopts a novel feedforward network called the Π-Σ network to identify the EMG features extracted through wavelet transformation. Experiments results show good convergence properties, high identification rate and especially faster learning speed compared with traditional methods
