least squares techniques meaning in Chinese
最玄乘法
Examples
- Least squares technique
最小二乘法 - The result of experiment validated the mathematical models and simulation methods . on the basis of theoretical models and experimental data , the least square technique was used to identify the indeterminable parameters in torque motor and parameters of magnetic fluid
在理论模型和实验数据的基础上,用最小二乘参数辨识的方法对力矩马达中的不确定参数及磁流体参数进行辨识,从而对添加磁流体的力矩马达进行了实验建模。 - In view of ill - posed characteristic of the equation , with variational principle , solving of a nonlinear hyperbolic equation is attributed to minimization of a functional . so the equation has unique solution through regularization theory . then variables of the functional are discretized and linearized with finite difference and nonlinear least squares techniques , accordingly minimization of the functional is converted into standard least square question
考虑到该方程具有病态特性，求得的解不唯一，具有一般数学物理反问题的特征，利用变分原理，将其转化为一个泛函的极小化问题，通过正则化处理，使原问题具有唯一解；然后应用有限差分思想和求解非线性最小二乘问题的方法，将泛函中的变量离散化和线性化，进而转化为一个标准最小二乘问题来求解。 - A blind joint angle and delay estimation method based on trilinear alternating least square technique in uniform circular array ( tals - cjade ) is also presented in section 3 , and a blind joint angle and delay estimation method based on complex parallel factor in uniform circular array ( comfac - cjade ) is given to improve the tals - cjade convergence performance
传统联合角度和时延估计方法在过载情况下(用户数大于阵元数)不能正确估计。与传统联合角度和时延估计方法相比, tals - ljade和tals - cjade算法具有较好doa和时延的联合估计性能,且在过载情况下仍有较好的性能。
