属性激活的认知原理分析

Cognitive Principle Analysis Based on Activation of Attribute

认知计算是当今研究的热点,而研究表明形式背景可用于认知计算.形式背景有多种表示方式,属性拓扑作为形式背景的一种新型表示方法,能够直观的表现出属性之间的关联关系及关联强度.从认知角度出发,提出属性拓扑的激活方法与对应的物理意义.即在设定的形式背景中,通过属性拓扑构造形式背景形成的认知网络.当新对象出现时,根据新对象所包含的属性进行属性拓扑的网络顶点激活,并分析激活部分的子网络结构间的关联关系.通过对关联关系的分析与运算,完成新对象的识别与原有形式背景知识完备度的衡量与更新.实验数据表明,属性拓扑激活机制符合人类认知新事物过程,并揭示了以认知为基础的形式背景扩充必要条件.

Cognitive computing is a hot research in today＇s society, and studies show that formal context can be used forcognitive computing. Formal contexthasa variety of representation methods, as a representation method of formal context, attribute topology can excess the relationships and correlative degree of attributes intuitively. This thesis analysis the method of activate attribute topology and it＇s corresponding physical meaning from the angle of cognition. Namely,formal context can form a cognitive network by constructing attribute topology in specific formal context. When new object present,according to the attributes of the new object to activate the net- work vertices in attribute topology and analysis relationships between the sub-network which is activated. Through association analysis and calculation, the recognition of new object can be realized, measure the degree of completeness and update prior knowledge of formal context. Experimental data suggest that activation mechanism of attribute topology conform to the process of human beings＇cognition about new things and revealed the requisite condition of expanding formal context which based on cognition.
