摘要
根据两类线性可分结构笛卡尔积的概念,定义了布尔空间中笛卡尔球的概念,证明了笛卡尔球是一类线性可分结构系.此外,还对以布尔空间中任意样本Ⅹ°为中心,与Ⅹ°之间Hamming距离为1的任意个样本与Ⅹ°组成的集合进行了研究,证明了这是一类笛卡尔球.为了对笛卡尔球进行规则提取,文中还分析了笛卡尔球的逻辑意义,建立了二进神经网络中判别笛卡尔球的一般方法,描述了这种判别方法的具体步骤,并通过一个实例说明了在二进神经网络中判别笛卡尔球的过程.
This paper gives the definition of Cartesian sphere according to Cartesian product of two Linear Separability(LS)structure series, and it proves that Cartesian sphere is a LS structure series. Furthermore, a kind of set, which is grouped by X'and any samples whose hamming distance with X^(?)are 1, is studied. It is proved to be Cartesian sphere. In order to extract rules from Cartesian sphere, the logical meaning of Cartesian sphere is analyzed, and a general judging method of Cartesian sphere is proposed. The judging steps are given in detail, and the judging process is described through an example.
