Study and Improvement of AprioriHybrid Algorithm in Mining Association Rules
Hantao Song · Jisuanji gongcheng · 2004
The paper analyzes the advantages and disadvantages of Apriori, AprioriTid and AprioriHybrid algorithm in mining association rules. To solve the bottle of AprioriHybrid algorithm, a support-matrix method to rapidly verify the 2-frequent itemsets is put forward. To accelerate the verification speed of the k-frequent itemsets, a simple and highly efficient method of minimizing the trade database is given. All these two methods improve the efficiency of AprioriHybrid method evidently.
