| 摘 要： | 本文针对当今各国高层领导和科学家十分关注并大力倡导的“数字地球”、“数字国家”、“数字城市”、“数字矿山”等科学工程构建中遇到的大量的多源、多维、多类型、多时态、多精度并具有非线性特征的联合数据处理问题的特点,建立了一个广义非线性动态联合数据处理模型及其相应的广义非线性最小二乘模型。针对该模型规模大、维数高的特点,借鉴多变量函数寻优的“变量轮换法”或“因素交替法”的思想、结合无记忆牛顿法,建立了一个解算算法,该算法将大规模的优化问题分解为两个较低规模的优化问题进行解算,降低了问题的规模,借助无记忆牛顿法,减少了存储量,特别适合大规模问题的解算。

| Abstract: | Aiming at characteristic of the data processing provided with non-linearity on multi-source multi-dimension multi-type multi-precision and multi-state surveying data in “digital earth”、“digital country”、“digital city”、“digital mine” advocated by many countries,a generalized nonlinear dynamic model and generalized nonlinear dynamic LS model for combined nonlinear processing on multi-source multi-dimension multi-type multi-precision and multi-state surveying data are established.Based on Newton's method and the variables alternating in optimization,an algorithm is put forward to solve large-scale generalized nonlinear dynamic LS problem. |
