| 中文摘要: |
| 针对误差反向传递(BP)网络模型收敛速度慢和易陷入局部最小的不足，提出将小波网络用于大坝变形监测的拟合和预报，综合了神经网络与小波分解在函数逼近上的优点。算例证明：小波网络模型的预测值与实测值拟合比BP网络模型的精度有较大提高。 |
| 英文摘要: |
| The wave-net theory is applied to establish the model for fitting and forecasting of dam deformation monitoring data. The wave-net adopts small wave function or scale function as the excitation function and possesses the advantage both of ANN and small wave analysis in the process of appoximation. The comparison of observation data with calculation shows that the accuracy of the model based on wave-net is much higher than that of BP model. |
