| 摘要: |
| 针对线性回归模型,在最小二乘意义下,提出一种基于改进进化策略的线性参数估计方法并用仿真实例检验其有效性.该方法是将进化策略与最小二乘法相结合并且对算法中的变异算子作了相应改进.算法参数估计精度较高,收敛速度快,自适应性强,能有效处理线性回归参数估计问题. |

| Abstract: |
| In terms of the least squares in linear regression modeling, a linear parameter estimation method is proposed basing on improved evolutionary strategy and its effectiveness is tested with simulation examples.The method combines evolutionary stratagy with the least square method, and the mutation operators of the algorithm are improved corespondingly.The parameter estimation algorithm has high precision, fast convergence speed, adaptabilily and can deal effectively with the problem of linear regression parameter estimation. |
