Minimum Support Count
Define a minimum support count to ensure itemsets appear frequently enough in transactions to be considered significant.
Minimum support count defines minimum
threshold in transactions that each rule must satisfy. When the number of transactions
is unknown, the support percentage threshold parameter can be tricky to set
appropriately. For this reason, support can also be expressed as a count of
transactions, with the greater of the two thresholds being used to filter out infrequent
itemsets. The default is 1
indicating that this criterion is not
applied.
