rank criterion matrix 中文意思是什麼
rank criterion matrix
解釋
秩標準矩陣-
While flda only can get one optimal discriminating vector, by maximizing the fisher criterion, due to that the rank of the between - class scatter matrix is at most 1 for binary - class problem
但類間離散度矩陣的秩最大隻能為1 ,決定了flda只能取一個判別方向(最大特徵值對應的特徵向量) ,無法利用其它方向的判別信息。
