"FP_Growth : must_contain"
Hi,
I use RapidMiner 5.0, and I want to do FPGrowth with parameter "must_contain". I hope that this parameter helps the algorithm (FP-Growth) use less memory.
So, I use Golf data set which is a sample data set coming with RapidMiner. Then, I set must_contain to "CAR = true".
The result is every item set contains CAR = true at the rightmost. It seems this parameter (must_contain) do nothing but
bring its value showed in the final result by attaching every frequent item set.
Does anyone give me some advice?
Thank you in advance.
