少样本视觉诱发电位获取研究

The estimation of visual evoked potentials with fewer samples

本文设计了两种从少样本中提取视觉诱发电位的方法。计算机仿真数据实验表明,ARMA—滤波器比最佳线性时变滤波器更优越。最后,我们通过临床研究检验了ARMA—滤波器,结果同样证明,ARMA—滤波器提取视觉诱发电位非常有效。

Two methods have been designed for estimating visual evoked poteatials with fewer samples. Results using simulated data show the performance of ARMA-filter to be greatly superior to the optimum linear time-varying filter. Then we tested ARMA-filter by clinical applica- tion. The results also show it highly efficient for estimating VEP.
