Comparative Study of Backpropagation and Improved Counter-Propagation Neural Nets in Structural Analysis and Optimization
摘要
In this chapter, two artificial neural networks, namely backpropagation neural net and the improved counter propagation neural net are applied to the analysis and optimal design of space structures. Different aspects of these nets and parameters affecting the performance of each net are investigated. Two examples are presented. A comparison has been made on the performance of these nets. The response of each net for the same input has been compared to illustrate their efficiency.
