Positive and negative association rule mining in Hadoop’s MapReduce environment
Sikha S. Bagui, Probal Chandra Dhar · Journal Of Big Data · 2019
In this paper, we present a Hadoop implementation of the Apriori algorithm. Using Hadoop’s distributed and parallel MapReduce environment, we present an architecture to mine positive as well as negative association rules in big data using frequent itemset mining and the Apriori algorithm. We also analyze and present the results of a few optimization parameters in Hadoop’s MapReduce environment as it relates to this algorithm. The results are presented based on the number of rules generated as well as the run-time efficiency. We find that, a higher amount of parallelization, which means larger block sizes, will increase the run-time efficiency of the Hadoop implementation of the Apriori algorithm.
