What is the impact of specifying a positive value in FP-Growth Parameter settings
As per operator documentations, the positive value parameter of the FP-Growth operator is defined as follows -
Description: This parameter determines which value of the binominal attributes should be treated as positive. The attributes with that value are considered as part of a transaction. If left blank, the ExampleSet determines which value is used."
I wish to know what the second part means - "If left blank,....". How does the exampleset determine which values are used? My dataset is comprised of semi-structured text-mined data and I'm trying to look for word associations. The output of Binominal to Polynominal operator gives me a word vector with true/false values. Should I still specify the positive value at FP growth? Thank you.
