In order to control the propagation of errors and enhance the accuracy of numerical solution , the wilson - 0 method is modified and the numerical stability of modified wilson - e method is analyzed 为有效控制误差的传递,提高计算精度,对wilson -法进行改进并分析了改进wilson -法的稳定性。
We use higher order spectra technique to extract the features of emg signals and classify them with a three - layered feed - forward network which implements the back propagation of error learning algorithm 通过对一段肌电信号的实验表明,这种的神经网络分类方法能够区分相应的上肢运动,对于肌电假肢的控制具有良好的应用前景。
