This operator create frequent item sets from a given stream.

The result stream creates a tuple with 3 attributes:

Parameter

Example

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)
