The document discusses frequent item-set mining, focusing on data mining techniques to analyze and summarize data for discovering interesting patterns. It highlights the importance of improving existing algorithms' efficiency and scalability, specifically addressing limitations in handling large datasets and real-time analysis. The main motivation is to enhance the efficiency of frequent item-set generation compared to existing algorithms like Eclat.

- 2. IntroductionIntroduction • Data mining searching for knowledge (interesting patterns) in data. • Data Mining is a process of analyzing data from different perspectives and summarizing it into useful information. • There are many techniques of Data Mining such as Classification, Clustering, Association rule , Regression etc. 2

- 5. MotivationMotivation Frequent item set mining include application like market basket analysis, modular fragment mining, web link analysis etc. It aims at finding regularities in the shopping behavior of customers of supermarkets, mail-order companies, on-line shops etc. In frequent itemset still there are some issues; that it not handle large amount of data, and real time analysis due to higher time complexity. 5
- 6. ObjectiveObjective Improve the work efficiency, scalability, and handle the large amount of dataset. Try to improve efficiency of existing algorithm. 6

- 10. Problem DefinitionProblem Definition In Eclat algorithm it is working only limited dataset. Improve only scalability of the item set. It can not handle memory size. Eclat algorithm does not take full advantage of Apriori property to reduce the number of candidate itemsets explored during frequent itemset generation. 10
- 11. ConclusionConclusion The survey of various frequent itemset algorithm is done with each having advantages, disadvantages and limitations over different parameters. The main motivation for frequent item set generation to increase the efficiency and scalability. We want to increase efficiency, scalability compare to Eclat algorithm or better. 11
