Decision on termination of R and D project based on region mapping model

The traditonal 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 influence the performance of neural network in pattern recognition. A region mapping model is proposed for decision on termination of an R and 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 the 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.
