Data mining, also named as kdd ( knowledge discovery in database ), is an advanced process, in which we can pick up many trustful, novel, useful and readable patterns from very large amounts of data
數據挖掘，也可以稱為數據庫中的知識發現（ knowledgediscoveryindatabase ， kdd ） ，是從大量數據中提取出可信、新穎、有效並能被人理解的模式的高級處理過程。 -
Experiments show that fpmine runs two times as fast as the most recently proposed algorithm fp - growth and saves half the memory ; moreover, our algorithm has a quite good time and space scalability with the number of transactions, and has an excellent performance in dense database mining as well ; spf has excellent time and space efficiency ; fpmine - spf algorithm has a far taster speed in association rules mining than the widely used apriori algorithm and has wonderful scalability. association rules mining always generates too many rules, which makes ii difficult to pick the valuable rules where from
實驗表明，在相同數據集上，與fp - growth演算法相比，演算法fpmine的挖掘速度提高了一倍以上，而所需的存儲空間減少了一半；隨著數據庫規模的增大，演算法fpmine具有很好的可伸縮性；對于稠密數據集，本文演算法也具有良好的性能； spf演算法具有極好的時空效率； fpmine - spf演算法挖掘關聯規則的速度遠快于較長期以來廣泛使用的apriori演算法，並有相當好的可伸縮性。 -
Data mining, also named as kdd ( knowledge discovery in database ), is a decision support method in which we can pick up many connotative, unkn - own, potential and useful knowledge or information mode from database or data warehouse. the knowledge that is discovered by means of data minning can reflect a certain facts and guide practice
數據挖掘（ datamining ） ，又稱知識發現，是利用各種分析工具在存放海量數據的數據庫或數據倉庫中提取隱含的、先前未知的、潛在有用的知識或信息模式的決策支持方法。通過數據挖掘發現的知識能夠反映一定的客觀事實，並指導實踐。 -
