surrogate data meaning in English
代用数据
Examples
- Application of surrogate data method in electromyograph analysis
替代数据法在肌电信号分析中的应用 - The results indicate that there is chaos in the real given fault gear signal and the surrogate data technique can identify chaos exactly
结果表明,齿轮故障信号存在混沌特征,替代数据法能对其进行准确识别。 - We find that all the results are quite different between each original emg and its ten surrogate data , i . e . emg is not a linear random noise , but a nonlinear deterministic signal ( though it does not like a low dimensional chaos )
也就是说,肌电不是线性随机的噪声,而是非线性的确定性信号(尽管它并不象是低维混沌) 。 - At first , construct ten sets of surrogate data for each emg data , then calculate the correlation dimension ( dcorr ) , correlation time , maximum lyapunov exponent ( a , ) , l - z complexity and approximate entropy ( apen ) of both the original emg data and surrogate data , and then compare them
构造这四例肌电信号的代替数据(各十组) ,分别计算原数据及其代替数据的关联维、关联时间、最大李雅普诺夫指数、 l - z复杂度和近似熵,我们发现,四例原数据的以上所有特征量都与各自所对应的十组代替数据存在明显差别。
