局部投影 meaning in Chinese

partial projection

Tested the volterra series " anti - noise performance . bring out the local projection method to reduce additional noise of chaotic time series in phase space
引入基于相空间的局部投影法对带噪的混沌时间序列进行了降噪处理，明显提高了volterra级数模型的抗干扰性能。
Contrast to the simple pca , the filter performance of the nonlinear local project noise reduction method has been improved greatly , it can recover the wave of the origin signal and trajectories of phase space even in low s / n ratio
与一般的主元分析相比，非线性局部投影滤波方法的性能明显提高，在较低信噪比下仍能较好地恢复原信号的波形和相空间轨迹。
2 . nonlinear local project noise reduction is studied on the basis of principal components analysis ( pca ) , the principle of this noise reduction is to approximate piecewise and linearly the dynamics and to process local principal components analysis
在主元分析( principalcomponentsanalysis ， pca )的基础上，研究了非线性局部投影滤波方法，该方法的原理是在相空间分段线性逼近动力系统并进行局部主元分析。
