平稳过程 meaning in English
stationary process
Examples
- Meanwhile , adjusting and optimizing the structure of investment distribution on education should be given attention . the innovation of this article are rest with : 1 ) applying granger causal relations methods to test causal relationships between education investment and economy growth ; 2 ) using time series data to built econometrical model , emphasizing education investment ' s long term feature ; 3 ) projecting future developments by arima model
本文主要创新点在于: ( 1 )利用格兰杰因果关系检验确定教育投资与经济增长之间的因果关系; ( 2 )利用时间序列数据进行建模时,着重体现了教育投资的长效性这一重要的特殊性质; ( 3 )利用齐次非平稳过程的arima模型对我国未来教育投资进行了预测。 - The main achievements are as follows : 1 . the load of power system is an unsteady stochastic process , whose observed value may exist some " unhealthy data " due to the effect of various factors . these unhealthy data , participating the training of neural network intermingled with normal data , badly affect the accuracy of load forecasting
电力系统负荷是一个随机非平稳过程，其负荷观测值由于受到各种因素的影响，可能会存在某些“坏数据”或“不良数据” ，这些数据夹杂在正常的负荷数据中参与神经网络的训练，严重影响了负荷预测的精度。 - 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。
