An Algorithm for Mining Frequent Closed Itemsets
The problem of mining frequent itemsetsplays an essential role in mining associationrules,but it is not necessary to mine all frequentitemsets,instead it is sufficient to mine the set offrequent closed itemsets,which is much smallerthan the set of all frequent itemsets.In this paper,we present an efficient algorithm,FCI-Miner,for mining all frequent closed itemsets.It basedon the improved FP-Tree(Frequent PatternTree),and used depth-first search strategywithout generating conditional FP-Trees andcandida-te itemsets. The experimentalevaluation on a number of real and syntheticdatabases shows that our algorithm outperformsprevious method in most cases.
