appropriate and effective use of fault diagnosis technology can heighten greatly the using life of all kinds of complex systems, reduce the maintenance expenses. The technology based on the nueral network and the one based on the fault tree model are two different kinds of diagnosis technologies that are more applied now, and each has its own advantages and disadvantages. This paper makes use of advantages...
In view of the security and stability of the large system today, the intelligent fault diagnosis becomes particularly importan. This paper proposes to apply the neural network knowledge to the fault diagnosis system, and takes the digital control module of some system for example. The paper also introduces the basic principle of neural network knowledge and the training algorithm of BP. Finally, according...
In this paper, two kinds of methods, namely additional momentum method and self-adaptive learning rate adjustment method, are used to improve the BP algorithm. Considering the diversity of factors which affect stock prices, Single-input and Multi-input Prediction Model (SIPM and MIPM) are established respectively to implement short-term forecasts for SDIC Electric Power (600886) shares and Bank of...
