Fpgrowth min support
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.
