查询词典 fuzzy theory

Although the panel logit models verify the effects of the explanatory variables consistently with the theory, the prediction accuracy is not as good as that of neuro fuzzy. In addition to the better out-sample prediction accuracy, neuro fuzzy also provides a more detailed and complicated relationship among the variables through the rule base mid 3-dimension graphics, which could be used for further theory development or modification Overall, the banking crises ca be predictable; however, each country needs different forecasting model. The mapping between the forecasting model mid data set characteristics ca be further developed for the future research.

实证结果显示，虽然Panel Logit之固定效果与随机效果模型皆验证了过去理论上各变数对银行危机之影响方向，但整体而言，其预测准确度并不比类神经模糊好；而类神经模糊除了提供更准确的样本外预测之外，其所建构的规则库与3D图提供较以往更为细腻的变数关系，此关系可作为未来理论发展之基础；整体而言银行危机可以被有效的预测，然而单一国家的预测结果显示不同的国家适用不同的预测工具，没有一项工具能够适用於所有的国家；而资料集属性与预测工具之对应关系可作为未来之研究方向。

It overcomes all the errors and shortcomings of Zadeh's fuzzy set theory: it correctly reflects different kinds of fuzzy phenomena in the natural world; set complement exists on it; it has uniform calculating formulas for membership; it satisfies all formulas of the classical set theory and is consistent with classical and normal thinking, logic and concepts.

新理论能克服Zadeh模糊集合理论的三个缺点和两个错误；能正确地描绘客观世界的全部模糊现象；有补集；隶属度有统一的计算公式；并且是经典集合系统的特例，能满足全部经典集合的公式，与正常思维、逻辑和概念一致。

Differs from classic set theory, fuzzy set theory uses a value in the closed interval [0,1] to denote the extent that an element belongs to the fuzzy set.

和经典集合论不同的是，模糊集合论用单位闭区间[0，1]中的某个数值来表示元素隶属某个集合的程度。

Based on Hutchinson niche and Guangxia Cao\'s definition, Fuzzy hypervolume niche evolves the theory of fuzzy niche: the niche is a fuzzy hypervolume; the niche of the species is a hypervolume with fuzzy boundary which is formed by the n-dimensional resources (time, space, temperature, humid, trophic,...) necessary for the species\' continuous existing and multiplying; membership of a point in the niche is equivalent to the adaptive degree of the species to the point of the environmental resources.

在Hutchinson生态位和Guangxia Cao的定义的基础上，模糊超体积生态位发展了模糊生态位理论：物种的生态位是可以使物种生存和不断繁殖的n维环境变量(时间、空间、温度、湿度、营养……)所形成的边界模糊的一个n维超体积；隶属函数表明n维资源空间的一个点x属于生态位的程度，也表明物种对环境资源的适应程度。
