Optimization of BP Arithmetic and Its Application in Geotechnical Engineering

The investigation and analysis of the non-linear coefficient that influence the convergence deeply is attempted, and the example in geotechnical engineering of this investigation production is also presented. The production has promoted the practicability of BP network. The practice has proved that the convergence speed and precision of the network will be improved observably if the BP arithmetic is mended by the rule and method given in this paper.
