机器学习算法反求水文地质参数

Identification of hydrogeological parameters based on machine learning algorithm

传统方法求解优化问题时,一般都是依据最小二乘原理来确定目标函数。鉴于这种方法没有考虑到原始测量数据的误差对计算结果及精度带来的影响。为此,提出机器学习算法改进传统的目标函数,同时结合双评价粒子群算法来求解水文地质参数。结果表明,该算法具有良好的收敛性和稳定性,求解效率高,简单易实现。

When solving optimization problem,the traditional method determines the objective function on the basis of the least squares principle without considering the influence of the error of the original measurement data on the results and the accuracy of calculation.Therefore machine learning algorithm is proposed in this paper to improve the general objective function and to solve the hydrogeological parameters in combination with particle swarm optimization of double evaluation.The result shows that machine learning algorithm has good convergence and stability as well as high solution efficiency,is simple and easy to realize.
