independent component analysis (ica) is a statistical technique that attempts to decompose multivariate data into many statistically independent components.
独立成分分析(ica)技术试图将多维数据分解成若干个相互统计独立的分量。
then, ica is performed on these pc axes to get the statistically independent ic axes.
然后对这些pc轴进行ica运算,得到相互统计独立的ic轴;
the noise sources are assumed to be statistically independent directional acoustic sources situated on the surface, and the effects of ocean environment on ambient noise are studied.
假设噪声源是统计独立分布在海面上的指向性点源,研究噪声源特性以及传播条件对海洋环境噪声场的影响。
