最优近似 meaning in Chinese

best fit approximation

Best fit approximation
最优近似
Then a new system of nonlinear equations can be formed from the variation gray of same point in multiple images and the optimum solution of the system can be obtained from gauss - newton and levenberg - marquardt algorithms , so that the normal vector at that point of the surface can be defined
再根据多幅图像上固定位置一点的灰度值变化列多个非线性方程，以gauss - newton算法和levenberg - marquardt算法为基础求非线性方程组的最优近似解，将选取点的法向量确定下来。
Then , based on the analysis of the combined forecasting precision sequence , the paper simplifies the model mentioned above , and gets an optimal model for calculating the approximate solution of the combined forecasting method , which is only a combination of two forecasting methods , and obtains the calculating formula of the optimal approximate solution . shen min ( transportation program and management ) directed by song bing liang
将上述两种单项预测法进行整合，首先建立了以预测方法有效性指标为目标函数的组合预测优化模型；其次在对组合预测精度序列分析的基础上，得到了求两组合预测方法权系数近似解的优化模型及最优近似解的计算公式； 4
