Research on Mining Frequent Itemsets Based on Bitwise AND Algorithm

According to the characteristics of the data flow, the article puts forward a new frequent itemsets mining algorithm based on bitwise and computation. Algorithm uses basic window for unit, and update sliding window in memory using arrays structure maintenance item of frequent information, finally by the frequent items between the bitwise and operations to get all the frequent itemsets. Algorithm in each basic window goes into the sliding window after dynamically update arrays, analysis and experiment shows that the algorithm has better performance.
