An Efficient Algorithm for Mining Closed Frequent Inter-transaction Itemsets

open access: yes, 2007
跨交易關聯規則可代表不同交易中項目間的關係,而近年來有愈來愈多相關的探勘演算法被提出,然而這些演算法會產生相當多的跨交易頻繁項目集合。找尋封閉性跨交易頻繁項目集合可使探勘的過程更有效率。 因此,在本篇論文中我們提出了一個探勘演算法叫「ICMiner」,以找尋封閉性跨交易頻繁項目集合。我們的方法可分為兩個階段。第一階段,將原始的資料庫轉換成領域屬性集合,使得每一個頻繁項目的領域屬性形成一個集合。第二階段,利用ID-tree去列舉出所有的封閉性跨交易頻繁項目集合。藉由ID-tree進行資料探勘 ...

Mining Closed Itemsets for Coherent Rules: An Inference Analysis Approach [PDF]

open access: yes, 2011
Past observations have shown that a frequent item set mining algorithm are alleged to mine the closed ones because the finish offers a compact and a whole progress set and higher potency.

Research Track Poster CFI-Stream: Mining Closed Frequent Itemsets in Data Streams

open access: yes, 2008
Mining frequent closed itemsets provides complete and condensed information for non-redundant association rules generation. Extensive studies have been done on mining frequent closed itemsets, but they are mainly intended for traditional transaction ...

An Efficient Subset-Lattice Algorithm for Mining Closed Frequent Itemsets in Data Streams

open access: yes, 2009
Online mining association rules over data streams is an important issue in the area of data mining, where an association rule means that the presence of some items in a transaction will imply the presence of other items in the same transaction. There are

cdeNDI:a Efficient Algorithm for Mining Frequent Itemsets

open access: yes, 2007
頻繁項目集的探勘,也就是從大型資料庫中找出頻繁項目集。這是許多其他問題的根本和基礎,像是關連規則、循序規則、分類和許多其他的課題。 在過去十年來,這個問題已經有了很大的進展。許多的演算法或改進現有演算法都不斷的被提出。然而,當我們降低最低支持度或是當我們遇到的資料庫是高度關連的時候,頻繁項目集的數目可能會極大。因此,如何應付密集資料庫仍然是一各具挑戰性的課題。 在這篇論文裡,我們提出cdeNDI這一種新演算法。這是以Eclat這個演算法為基礎,將closed itemsets和non ...
