Thus , i can use them as hash keys , lists of strings to be searched , etc 這樣,我可以讓它們作為散列的鍵、將要被檢索的字符串列表,等等。
Thus , it is possible to have an array of hashes or a hash of arrays or a hash of hashes or an array of arrays n - dimensional array 這就允許perl生成一個散列的數(shù)組、數(shù)組的散列、散列的散列、或是數(shù)組的數(shù)組(多維數(shù)組) 。
The paper propose a new means to mine multidimensional association rules based on multidimensional frequent items set by two steps . firstly we obtain inter - dimension association rules by combining data cube technique with apriori method efficiently 本文中對基于多維的頻繁項集的算法進行了探索和算法優(yōu)化,尤其是通過采用了維搜索和散列的技術(shù)方法而使得系統(tǒng)的挖掘性能大大提高。
