"RapidMiner Association Rules / transaction based dataset"
Hello,
maybe someone here has already had experiences with this topic. I have itemsets that represent orders. The format is:
OrderID Item
1234 10
1234 12
1267 3
1288 3
My problem is, that the nominal-2-binominal operator doesn`t support this format. Using this Operator, it creates binominal datalines for each row. What i need is a grouping by the corresponding OrderID.
I spend a lot of time for finding a solution but i didn`t get any answers yet - although it seem to represent a common data-format.
Thanks for youre help !

Well, I think the FP-Growth Operator needs the following resulttable:
OrderID Item_10 Item_12 Item_3
1234 true true false
1267 false false true
1288 false false true
I want to search for association rules in the item sets. Therefore i have to use the FP-Growth Operator.
Thanks for your'e reply
OrderID Item_10 Item_12 Item_3
1234 true true false
1267 false false true
1288 false false true

I'm not sure what your desired output is. This?
OrderID Item
1234 10, 12
1267 3
1288 3
Something else?
