Missing W-Apriori Algorith
Hi everyone,
I am trying to look for the W-Apriori operator to use while doing a homework assignment. I can't find it anywhere when looking for it, even on the filter text box on the left hand side. I can find the FP-growth one alright. Worth noting I just accepted updates to Rapidminer 5.
Is that a known issue / do I need to install anything to get to use this operator?
Thanks a lot for helping out!

This worked - thank you SO much!
I was able to download the extension and can see the operator now, but the output is missing the actual itemsets! I left all default values as is, this is the output:
W-Apriori
Apriori
=======
Minimum support: 0.1 (3 instances)
Minimum metric <confidence>: 0.9
Number of cycles performed: 18
Generated sets of large itemsets:
Size of set of large itemsets L(1): 12
Size of set of large itemsets L(2): 3
Best rules found:
It doesn't list the actual itemsets. I am using Rapidminer 6.0.006 - any ideas?

Hi,
the apriori algorithm is about generating association rules - which are delivered by the operator. The frequent item sets are only an intermediate result.
If you actually want frequent item sets, you can use FP-Growth to get them.

You need to install the Weka extension. Go to Help->Updates and Extensions (Marketplace) then search for Weka. Follow the instructions to install this.
