Artificial neural network is a kind of implicit expression without explicit expression as statisticalregressionmodel, and it is its disadvantage.
人工神经网络不具备统计回归模型的显式表达形式,是一种隐式模型,因而有它的缺陷性。

A concrete dam deformation forecasting model is established based on the particle swarm optimization (PSO) algorithm and the traditional multi-statisticalregressionmodel.
Then it establishes a stepwise statisticalregressionmodel. Finally, the model prediction effect is comparative analysis by comparing the characteristic parameters of the model.
