基于min型表现外延的反馈外延外包络

INNER ENVELOPE OF CONCEPT EXTENSION BASED ON MINIMAL FORM REPRESENTATION EXTENSION

相对于max型表现外延,给出min型表现外延的定义,利用min型表现外延构造了概念关于因素的min型反馈外延.研究了min型反馈外延与概念外延以及复杂因素min型反馈外延与简单因素min型反馈外延之间的关系,得到了与min型反馈外延相关的一些重要性质.定义了min型反馈外延外包络,给出一种从概念外延“内部”对概念外延进行逼近的方法.

Corresponding to the max-type representation extension, the rain-type representation extension is defined in the paper, and then the min-type feedback extension is proposed. The relationship between the min-type feedback extension and the concept extension as well as between the min-type feedback extension on complicated factors and on simple factors is discussed. Some important properties on the min-type feedback extension are described. The outer envelope of min-type feedback extension is also defined, which can be used to approach concept extension from the inner.
