摘要
针对属性散射中心特征提取过程的参数优化步骤中出现的局部最优解问题,提出了一种基于混沌方程的参数优化混合算法,以避免参数优化过程局部最优,并结合Matlab提供的优化函数迭代,算出最终的属性散射中心参数。实验表明,这种优化混合算法能有效避免参数优化过程陷入局部最优,从而提高了参数优化结果的准确性。
Locally optimal solution may appear in the optimization step of the feature extraction of attributed scattering centers. In order to solve this problem, the paper proposes a method based on chaos equation, which can help to escape the locally optimal solution. Except that, the method uses the optimization function supported by Matlab to get the solution of attributed scattering centers parameters. At last, the method is testified problem. As a result, the accuracy of the by experiment efficient to solve the locally optimal solution optimization can be improved.
