task value attribute 中文意思是什麼
task value attribute
解釋
任務值屬性-
There are three means to decrease the number of attributes : delete irrelevant attributes to the task using fisher ' s discriminant ratio ; merge correlate attributes according to pearson ' s correlation coefficient ; reduce the dimensionality of the attribute vector by singular value decomposition
在屬性選取時根據fisher函數把對分類影響小的屬性刪除,由pearson ' scorrelationcoefficient將相關聯的屬性合併,用singularvaluedecomposition減少屬性向量空間的維度。
