Prediction of Railway Foundation Settlement Based on the BP Neural Network Model

Based on the method of BP neural network,a foundation settlement of BP neural network prediction model was established for a railway subgrade in HeFei area China. In the model, the previous field monitoring data was used as the training sample and the later settlement was predicted. The model was used for four test sections of the railway subgrade. The results showed that for the four test sect...

Endpoint Prediction of BOF Steelmaking based on BP Neural Network Combined with Improved PSO

This paper concerns the endpoint estimation of the basic oxygen furnace (BOF) steel making process. More specifically, a back propagation (BP) neural network is employed to estimate the endpoint carbon content and the endpoint temperature of BOF, and an improved particle swarm optimization (PSO) algorithm is proposed to optimize the prediction model for improving the accuracy of the endpoint pr...

Regional GDP Prediction Based on Improved BP Neural Network Model

In this paper, an improved BP neural network model is proposed. In the model, the momentum factor can improve the training speed and avoid falling into local minimum. Steepness factor and adaptive learning rate can improve the convergence speed. The genetic algorithm is used to solve the problem of low training speed, low accuracy of prediction and easy to fall into local minimum of BP neural n...

Research on the Evaluation Methods of Bid of Construction Project Based on Improved BP Neural Network

Bid and tender is the core stage in construction project, however, many evaluation factors can be handled easily by qualitative analysis, which is hard to avoid subjectivity. In this paper, a new evaluation index system is proposed to use quantitative analysis in order to avoid error which is induced by subjectivity, firstly. Secondly, an improved BP neural network is proposed as an evaluation ...
