rough functional dependency

基本解釋

The accurate and approximate measures of rough functional dependency are proposed in this paper in order to find potential and interesting patterns for rough relational database.
爲(wèi)了發(fā)現(xiàn)粗糙關(guān)系數(shù)據(jù)庫中潛在的和有趣的模式，提出竝研究了粗糙函數(shù)依賴的近似度量和精確度量。
The introduction of approximate theory of rough functional dependency will accelerate the development of knowledge discovery for rough relational database and extend its research field.
該度量的提出及其性質(zhì)的研究有利於粗糙關(guān)系數(shù)據(jù)庫的知識發(fā)現(xiàn)及數(shù)據(jù)查詢的研究，竝且進(jìn)一步擴(kuò)大了粗糙關(guān)系數(shù)據(jù)庫的研究領(lǐng)域。
