提出了最小二乘支持向量机(LS-SVM)与BP神经网络的最优加权组合模型。通过实测数据对比分析了LS-SVM、BP神经网络、基于总体最小二乘算法(TLS)的二次多项式曲面拟合和最优加权组合模型的精度,结果表明最优加权组合模型的精度优于其他模型。
The optical weighting combined model of LS-SVM and BP Neural network is proposed.According to the measured data,the accuracy of LS -SVM model,BP Neural network model,Quadratic polynomial curve surface fitting based on total least-square algorithm and optimal weighting combined model are compared and analyzed.Test results show that the precision of optimal weighting combined model is better than others.
