Data Mining Area Known As Closed Itemset Mining Essay

Good Essays

This master thesis addresses the data mining area known as closed itemset mining. The work program includes analysis a one of well-known algorithms from the literature, and then modifying these algorithm in order to optimize their performance by reduce the number of frequent pattern. Data mining is the procedure of getting new patterns from large amount of data. Data mining is a procedure of finding of beneficial information and patterns from huge data. It is also called as knowledge discovery method, knowledge mining from data, knowledge extraction or data/ pattern analysis. The main goal from data mining is to get patterns that were already unknown. The useful of these patterns are found they can be used to make certain decisions for development of their businesses. Data mining aims to discover implicit, already unknown, and potentially useful information that is embedded in data. Frequent itemsets play an main role in a lot of data mining tasks that try to get interesting patterns in databases, such as association rules, clusters, sequences correlations, episodes and classier. Although the number of all frequent itemsets is usually very large, the subset that is really interesting for the user typically contains only a small number of itemsets. Therefore, the model of constraint-based mining was introduced. Constraints provide focus on the interesting knowledge, thus decrease the number of patterns extracted to those of possibility interest. Additionally, they can be
