Research of AprioriHybird algorithm and application in network situational awareness

The article analyzes the advantages and disadvantages of Apriori, AprioriTid and AprioriHybrid simply. To solve the bottleneck of AprioriHybrid algorithm, a kind of Hash-based method to condense candidate itemset is presented, and providing the corresponding algorithm. Finally the experiment proves the efficiency of improved AprioriHybrid-H is better than AprioriHybrid Algorithm's, there is strong guiding significance to apply in the concrete network situational awareness systems so that excavating a large number of interesting association rules, understanding the current network status, judging and taking measures timely.
