This paper makes further research on BP neural network algorithm on the basis of the existing literature. It pointed out the problems in the inherent algorithm, as well as the causes were presented. This research also proposed the BP neural network was difficult to achieve the desired effect when applied to solve the forecasting problems, and then the reasons of that were analyzed, and this point...
In recent years, BP neural network is widely used in the field of nonlinear prediction. This paper proposes a variable step size BP algorithm for forecast of investment on inventory clearance and the framework to improve prediction accuracy and reduce investment risks.
Recently, international construction claim plays an important role in the management of the construction contract. In this paper, aiming at the drawbacks of traditional BP arithmetic, an improved BP neural network is introduced based on the LM arithmetic so as to accelerate the convergence speed. A forecast model of nonlinear system is set up based on the LMBP neural network by studying all of the...
There are situations of many results and many reasons in the fault diagnosis. The training method of former neural network is supervised by teachers only could forecast or diagnose what kind of failure has occurred to the failure that possibly occurs. As a result of equipment's complexity, it is difficult to find the source of fault accurately and rapidly in practical application even if we know the...
