RESEARCH ON OPTIMIZATION OF APRIORI ALGORITHM BASED ON CLOUD COMPUTING AND MEDICAL BIG DATA
Abstract:This paper analyzes the association rule algorithm in medical data mining technology, on the premise of association-rule-based classical Apriori algorithm, interest measure threshold is introduced to improve the algorithm. At the same time, with the usage of cloud computing and cloud platform Hadoop, a new association rule algorithm of medical data mining, based on MapReduce, interest measure, confidence coefficient, and support degree, is put forward. At the end of this paper, a simulation experiment is carried out based on Hadoop, which proves the superiority of the improved algorithm.
