１．４扩展δ算法及其在数据处理中的应用张其欣对于Ｎ个变量Ｍ个测量样本值ｂ＿Ｍ，求解线性判别函数问题可表示为：设：Ｔ为转置。（１）式可用伪逆矩阵来求出Ｗ；这种精确代数分析方法不仅会碰到Ｘ￣Ｔ为奇异性矩阵的困扰，更主要的是有局限性。例如对异或问题的分类，...
1.4 Extended δ algorithm and its application in data processing Zhang Qixin For N variable M measurement samples b_M, solving linear discriminant function problem can be expressed as: Let: T be transpose. (1) can be used to find the pseudo-inverse matrix W; This exact algebraic analysis will not only encounter X ~ T singularity matrix problems, more importantly, there are limitations. For example, the classification of XOR problems, ...
