【期刊论文】Extracting fuzzy if-then rules by using the information matrix technique☆
黄崇福, Chongfu Huanga, * and Claudio Moragab

In this paper, we use the information matrix technique to extract fuzzy if-then rules from data including noise. Witha normal diffusion function, we change all crisp observations of a given sample into fuzzy sets to make an information matrix. We extract rules according to the centroids of the rows of an information matrix. These rules are integrated into an additive fuzzy system with the same rule weight. Such fuzzy systems can be used as adaptive function approximators. Simulations show that this method is very effective compared with the conventional least-squares method and neural network. The best advantage of the suggested method is that, it may be the simplest way to extract fuzzy if-then rules from data.

【期刊论文】A DEMONSTRATION OF RELIABILITY OF INTERIOR-OUTER-SET MODEL*
黄崇福, CHONGFU HUANGa, b, †
,-0001,():
-1年11月30日
In this paper, we execute some computer simulation experiments to demonstrate the reliability of interior-outer-set mode. The experiments are done for the normal distribution, exponential stribution and Poisson distribution. The simulation results show that the interior-outer-set model is more reasonable than the histogram model because the errors from the interior-outer-set model is smaller. The most important issue is that the possibility-probability distribution (PPD) (calculated by using the interior-outer-set model) coordinates the practical situation: it is impossible to assign a unique probability value for an event with incomplete information.

介绍了风险研究的基本内容,探讨了自然灾害风险分析的基本原理,从风险的本质和自然灾害的具体表现可以看出,自然灾害风险的分析,依赖于一整套贯穿于致灾因子到灾害影响的、能前后相联的模型,本文对各个环节的模型提出了一些原则性的建议。
