5. Linguistic-Valued Approximate Reasoning With Lattice Ordered Linguistic-Valued Credibility

Li Zou, Yunxia Zhang, Xin Liu
Pages: 53 - 61
Linguistic terms are often used to represent the truth degree or credibility degree to manage the uncertainty or imprecision as one of popular ways of knowledge representation in the perception-based decision making problem. This present work represents the credibility of uncertain knowledge using linguistic...

6. Selection of Encoding Cardinality for a Class of Fitness Functions to Obtain Order-1 Building Blocks

Hongqiang Mo, Zhong Li, Lianfang Tian, Xiang Tian
Pages: 62 - 74
Encoding plays a key role in determining the optimization efficiency of a genetic algorithm. In the optimization of a continuous function, binary encodings are normally used due to their low coding-alphabet cardinalities. Nevertheless, from the viewpoint of building-block supply, it is remarked that...

7. The Evidential Reasoning Approach to Medical Diagnosis using Intuitionistic Fuzzy Dempster-Shafer Theory

Yanni Wang, Yaping Dai, Yu-wang Chen, Fancheng Meng
Pages: 75 - 94
For medical diagnosis, fuzzy Dempster-Shafer theory is extended to model domain knowledge under probabilistic and fuzzy uncertainty. However, there are some information loss using discrete fuzzy sets and traditional matching degree method. This study aims to provide a new evidential structure to reduce...
