协方差平稳过程的英文
covariance stationary process
例句与用法
- The relationship of the spca , pca and kpca are established . according to the covariance stationary processes , spca arithmetic also has certain stability and convergent similar to pca arithmetic
由协方差平稳过程，得到谱主成分分析算法也有类似于主成分分析算法的稳定性和收敛性。 - In this thesis , based on principal component analysis ( pca ) , covariance stationary processes and spectral analysis theory of linear operator , spectral principal component analysis ( spca ) is put forward
在主成分分析的基础上，基于协方差平稳过程理论和线性算子谱分析理论，本文提出了谱主成分分析。 - We proof the covariance function of covariance stationary processes is equivalent with mercer kernel function . that is , the covariance function of covariance stationary processes is a mercer kernel function ; in reverse , for a given mercer kernel function , there exists a covariance stationary processes , and the covariance function corresponded to this covariance stationary processes is the given symmetry positive - definite kernel function . it means that the covariance function is equivalent to symmetry positive - definite kernel function
首先建立了协方差平稳过程的协方差函数与积分方程中对称正定mercer核函数的等价关系，即协方差平稳过程的协方差函数是对称正定mercer核函数，反过来，对给定的对称正定核函数，证明了存在协方差平稳过程，使得此协方差平稳过程对应的协方差函数恰好为给定的对称正定核函数，这说明协方差函数和对称正定核函数是等价的。
