6.2.1 Apriori Algorithm: Finding Frequent Itemsets by Confined Candidate Generation Apriori is a seminal algorithm proposed by R. Agrawal and R. Srikant in 1994 for mining frequent itemsets for Boolean association rules [AS94b]. The name of the algorithm is based on the fact that the algorith...

The Apriori algorithm generates the frequent item sets, but the accuracy of that frequent set update is very less, there have been several methods proposed to improve its performance. Apriori algorithm consumes more time for scanning the database repeatedly. In this paper proposed a Re-adapted ...
