an itemset that occurs at least a certain minimum number of times, having an itemset frequency of ≥ (i.e., only combinations that occur with higher frequency)
an itemset that occurs at least a certain minimum number of times, having an itemset frequency of ≥ (i.e., only combinations that occur with higher frequency)
• absolute support of an itemset is its frequency count • relative support is the frequency count of the itemset divided by the total size of the dataset
