1) amplitude standard deviation
振幅标准差
1.
After obtaining features parameters of different mental tasks by using the amplitude standard deviation of time-frequency window,the pattern recognition method of K-neighbors was applied to optimal classification.
对思维脑电信号进行Hilbert-Huang时频预处理,经经验模式分解后,得到多阶固有模态分量,然后将经HHT变换后的时频窗口内的振幅标准差作为不同心理作业信号特征,再应用K-近邻对思维脑电信号进行分类决策。
2) standard amplitude
标准振幅
3) amplitude normalization
振幅标准化
4) amplitude error
振幅误差
1.
All errors are equivalent to phase and amplitude errors and thus the standard deviations of the phase and amplitude error are calculated.
