广义非线性动态最小二乘理论在"数字山东"构建中的应用

“数字山东”是“数字中国”的一项宏伟科学工程,是推动山东省跨入信息社会的主题。构建“数字山东”这一科学工程的基础是数据,其数据具有海量、多源、多维、多类型、多时态、多精度、多尺度、多分辨率并具有非线性特征等特点,要将这海量数据统一管理、准确、唯一地可视化表达,首先要进行数据处理。针对“数字山东”中海量空间数据具有多样化、动态性和非线性等特点,应采用广义非线性动态最小二乘法进行数据处理。本文重点讨论了“数字山东”中的数据及其特点,处理这类海量数据的广义非线性动态最小二乘法的基本理论和基本方法及其数学模型,这一理论方法在“数字山东”构建中的数据处理方面的主要应用。

Application of Generalized Nonlinear Dynamic Least Squares Theory in Building Digital Shandong

Digital Shandong" is a grand scientific engineering in the "Digital China", which is a subject to promote Shandong Province to enter the information society. Data are the basis and key to build the "Digital Shandong". The data have characteristics of enormous capacity, multi-source, multi-dimension, multi-type, multi-tense, multi-measure, multi-accuracy, multi-resolution and nonlinearity as well. Data with enormous capacity should be uniformly managed and precisely visualized. Therefore, the generalized nonlinear dynamic least squares theory can be used to process the data. Data and their characteristics in building the "Digital Shandong" are mainly discussed in the paper. Then the basic theory, method and application of generalized nonlinear dynamic least squares method in the data processing to build the "Digital Shandong" are given.
