How to construct the corss-product/cartesian-product attribute in RapidMiner
If attributes A1 (level=1,2 or 3) and A2(contribution=1,2,3, or 4) are known, now want to construct the new attribute A3 = A1 X A2 , eg. one new attribute will be (level=2,contribution=3),
Which operator should I use? the AttributeConstruction, AttributeMerge or other? I fail to see the corss product formula available in AttributeConstruciton, and as the cross-product consider the vector or space position as I see, so the simply merge two attributes may not be appropriate either.
So how can I build the new attributes, appreciate your suggestion.
