基于决策树的中毒诊断专家系统实现
Implementation of poisoning diagnosis expert system based on decision tree
【摘要】 为了使中毒诊断专家系统能快速确诊,在分析传统决策推理机制的基础上,提出一种改进的推理机制,应用到系统中,并给出了具体实现方法。该系统根据初始中毒症状,充分考虑中毒症状对确诊的贡献及诊断代价,动态构建决策树,然后通过启发式推理,最终得到确诊结果。系统测试结果显示基本达到预期目的。
【Abstract】 In order to judge the poisoning quickly through poisoning diagnosis expert system,after analyzing the failure of previous model of inference,a novel model of inference was put forward with which the expert system applies,and the particular method of implementation was introduced.This system firstly set up a decision tree according to the symptoms doctor known and thinking enough of its diagnostic contribution and diagnostic expense,and then found the result(the cause of poisoning) through repeatedly heuristic deduction.System test shows that it achieves the desired result.
