Based on the BP Neural Network Optimization Application Research of the Construction Site

Abstract

Artificial neural network (ANN) is a discipline which is used to calculate the nonlinear problem in the late 1980s. The BP neural network is widely used. It has been widely used in engineering because of its nonlinear mapping ability, self-learning ability, associative memory ability, parallel information processing mode and its excellent fault tolerance ability. The main functions of the system are pattern recognition, function approximation, data compression and prediction. Because of the huge amount of computation in the practical calculation of BP neural network model to help launch by the American Mathwork company MATLAB software, MATLAB software and BP neural network toolbox, can efficiently complete the project tasks. MATLAB software package BP tools function in mathematical calculation, graphic calculation, computer simulation and other aspects to provide a convenient tool for the research and design of neural network, to overcome the complexity of the problem, the advanced computer language programming language is simple, convenient debugging program, high operation efficiency, has very important application prospect.
