基于可信度方法的甲状腺疾病诊断模型

A thyroid expert system model based on certain factor

研究并设计了一个基于可信度方法的甲状腺专家系统不确定性推理模型,在该模型中对甲状腺知识的表示、推理控制策略的选择、不确定性算法的建立进行了具体详细的研究,使文中所研究的不确定推理方法得以实现.讨论了可信度模型,给出了不确定性推理网络的算法描述,并且将理论研究的结果运用于甲状腺专家系统模型框架的设计和实现,对不确定性推理的应用进行了有益的探讨.

A thyroid diagnosis expert system model based on certain factor was designed.In this model the author discusses a lot about the thyroid knowledge expression,the choice of reasoning control strategy and the setup of uncertainty algorithm,so that Uncertainty Reasoning Methods studied in the paper are realized.The article discussed Certain Factor Method model and described the algorithm of indefinite inference network as well as the realizing method.The theoretic result was applied in designing and implementing the thyroid expert system model and example was given.Application of indefinite inference is also approached.
