基于扩展BP网络道路造价预测影响因素确定

Determination of influencing factors of road cost prediction based on extended BP network

为有效确定影响道路造价的关键因素,设计采用一种基于中心性的关键因素筛选方法,并基于BP神经网络模型分析了道路工程造价的影响因素。

In order to effectively determine the key factors that affect the road cost, a key factor screening method based on centrality is designed and the factors affecting the cost of road engineering are analyzed based on the BP neural network model.
