本文先分析了多目标定值的问题环境,然后介绍农业施肥专家系统工具 AFshell 中建立的一个权值学习模型。该模型以二项系数加权和法为基础进行初始权系数的获取,以教导注入式方式进行权向量调整,并能通过实例运行进行权向量的完善.这种学习模型具有推广性,也可用于其它多目标定值的问题领域。
This paper first analyzes the problem environment of multi-objective valuation and then introduces a weight learning model established in the AFshell of agricultural fertilization expert system. In this model, the initial weight coefficient is obtained on the basis of the binomial coefficient weighted sum method to teach the injection-style method to adjust the weight vector, and to perfect the weight vector through the operation of the examples.This learning model is generalized and can also be applied to Other multi-goal setting problem areas.
