WebJun 1, 2011 · A higher minimum support will obviously lead to less ‘frequent itemsets’ being found. The user also chooses a minimum confidenc minConf that will be used when performing rule mining. Analogously, a higher minimum confidence will lead to less association rules being found. ... See FPGrowth::buildFPTree() in my implementation, … WebminConfidence: minimum confidence for generating Association Rule. Confidence is an indication of how often an association rule has been found to be true. For example, if in the transactions itemset X appears 4 times, X and Y co-occur only 2 times, the confidence for the rule X => Y is then 2/4 = 0.5.

WebThe first step is to scan the database to find the occurrences of the itemsets in the database. 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. The second step is to construct the FP tree. For this, create the root of the tree.
