First, by redefining the within class scatter matrix and the between class scatter matrix, a new null space method was presented.
首先，通过重新定义样本的类内散布矩阵和类间散布矩阵，提出了一种新的零空间法。

I will provide a uniform explanation for OSC in this dissertation: V2 (with its null subject and null object) is essentially a purpose clause modifying the matrix clause.
The optimal feature vectors are extracted from the null space of intrapersonal locality preserving difference scatter matrix, which avoids the singularity and the SSS problem is solved.
