Frequent pattern is an intrinsic and important property of datasets. It acts as foundation for many essential data mining tasks, it uses in : Association, correlation, and causality analysis,sequential, structural (e.g., sub-graph) patterns,pattern analysis in spatiotemporal, multimedia, time-series, and stream data Classification, frequent pattern analysis ,cluster analysis (frequent patternbased clustering),data warehousing( iceberg cube and cube-gradient) ,semantic data compression. Closed Patterns and Max-Patterns: An itemset X is closed if X is frequent and there exists no super-pattern Y %u05db X, with the same support as X ,closed pattern is a lossless compression of frequent patterns As Reducing the number of patterns and rules. An itemset X is a max-pattern if X is frequent and there exists no frequent superpattern Y %u05db X Example : Suppose a database contains only two transactions , , let the minimum support count threshold be min_sup = 1 What is the set of closed itemset? {a1, %u2026, a100}: 1
