Modify on Rapid Miner operator

cping

Hi everyone,

I am new here. I would like to modify FPGrowth generator in rapidminer to suit my need. What I need is adding certain rule or constraint into this FPGrowth to filter the frequentItemSets. So, can you guys give me any useful suggestion?

Thanks

I wouild suggest you to create a new plugin (I guess a guide for that is in RM tutorial), which will contain your new class (a copy of the code of the FPGrowth class). Than you can make any changes you like.
Also do not forget to define your new class in operator.xml file.
