Hi,

I created a sample dataset that goes like this: itemIditemCount1Product111Product343Product155Product173Product21
CustomerId
I tried to use this in the "Masket Basket template in Rapidminer but it gives me the error "The example set contains non-nominal attribute sum(itemCount)_Product1 which is not allowed for FPGrowth".

What am I doing wrong?
Can give me an advice?

Thank you in advance

    Hi,

    The frequent itemset generator only tolerates binominal attributes, which means that you'll need to do some pre-processing. As for advice I'd say that working through help->tutorial actually saves many hours of grief; RM has its own jargon, and until you know it you remain in the vale of tears!

    So do that, and then activate a breakpoint just befor the FPGrowth operator, just to check that your data is binominal. If any of that does not make sense then you really should run through the tutorial.

    Good luck!
