Apriori is a seminal algorithm proposed by the researchers. Many researchers have been done to make mining frequent itemsets efficient and scalable. The name of the Apriori based on the fact that the algorithm uses prior Knowledge to find the frequent itemset. Apriori algorithm in data mining is one of the most frequently used algorithms for finding the frequent itemset in database. Efficiency has been concerned for several years in data mining for finding frequent itemsets. Various improved version of Apriori algorithm are proposed. This paper presents an idea about the improved versions of Apriori algorithm and their performance comparison with Apriori algorithm.
