WebThe (frequent) pattern-growth method mines the data set in a divide-and-conquer way: It first derives the set of size-1 frequent patterns, and for each pattern p, it derives p ’s projected (or conditional) database by data set partitioning and mines the projected database recursively. WebIf itemset has no superset with the same frequency, then the itemset is called Closed frequent itemset. Max frequent itemset. If itemset does not have any frequent supersets, …

This step is the same as the first step of Apriori. The count of 1-itemsets in the database is called support count or frequency of 1-itemset. http://hanj.cs.illinois.edu/cs412/bk3/06.pdf derby bin collection 2021

WebA pattern is closed if none of its supersets has the same support as it does. Closed patterns retain the support information of frequent patterns. The complete set of frequent patterns can be derived from the set of frequent closed patterns without information loss. A maximal pattern must be a closed pattern, but not vice versa. WebClosed patterns can be viewed as a lossless compression of frequent patterns, whereas maximal patterns can be viewed as a simple lossy compression of frequent patterns. … derby bearings limitedWebFrom the lesson.
