This operator create frequent item sets from a given stream.
The result stream creates a tuple with 3 attributes:
This example uses FP-Growth for finding frequent item sets. it does not need any parameters in algorithm
/// support is 3 out of 1000 transactions fpm = FREQUENTPATTERN({support=3.0, transactions=1000, learner = 'fpgrowth'}, inputoperator) /// support is 60% out of 1000 transactions, so it is equal to a support of 600.0 fpm = FREQUENTPATTERN({support=0.6, transactions=1000, learner = 'fpgrowth'}, inputoperator) |
