"Association rule mining"
Contributor I
Hi,
I have a dataset formatted as follows:
1 10 20 30 51
2 23 45 67
3 34 56 77
4 56 77 89
5 68 66 90
The first column represents the transaction -id. From second column onwards the numbers represent the item nos. purchased by a customer. I would like to generate association rules and frequent itemsets.
I have rapiminer 4.0.
How can i use RM4.0 to get Frequent itemset and association rules
Thanks and Regards

2. Association analysis is for large *binary* datasets, meaning 1s and 0s only
el chief ist right with both points. Let me add that you could transform your data set by preprocessing operator within RapidMiner in order to get such a binary data set. Search for example for Pivoting here in the forum in order to get more information about this.
