摘　　要：针对传统的BP网络训练时收敛速度缓慢 ,容易陷入局部极小 ,并且实际分类准则与训练准则不一致的缺陷 ,提出了R&D项目中止决策模式识别的区域映射模型 .模型从根本上保证了分类准则与训练准则的一致性 ,具有比BP网络更快的训练速度和更高的识别率 .案例研究表明 。The traditional BP neural network has slow convergence speed and may easily fall into local minimum points,and its classification rule is not consistent with its training rule. All these reasons influence the performance of BP neural network in pattern recognition. Region mapping model is proposed for decision on termination of a R&D project,which guarantees inherently the consistency of classification rule with the training rule. The convergence speed of region mapping model is faster than that of BP neural network, and the model has a good identification ratio. The result of an empirical study shows that region mapping model is an effective method of pattern identification for decision on termination of R&D project.
