CUI Yong, ZHAO Cheng-lin (Department of Geoscience, The University of Petroleum, Changping 102200,Beijing, China)
The principle, model and algorithm of neural network technique are discussed. The problems remaining to be solved in the application of the technique are pointed out, and they include preparation of data, expand of mode, determination of the number of hidden layer elements, and treatment of weight coefficients, step length, momentum factor and expressible factor in the process of computation. The application of neural network to lithologic identification being taken as an example, and the approaches of solving the problems are proposed.
