Hi team
Please help me in using process "Applying Association Rules" to a dataset.
I have a data with CustomerID, ProductName, Revenue
I created a set of association rule based on the above metrics (revenue used as weight)
Now I want to create a data set which has one more column(s) showing Recommended product based on association rules created above.

I tried using process"Applying Association Rules", but it asks for some binary variable, actually it says revenue should be binary!!!

Please help and suggest solution to this

Thanks
Deepak

Hi Deepak,

most probably you have applied FP-Growth before Create Association Rules. You should pass the same data set you passed into FP-Growth into Create Association Rules.
If my assumption is not true, please provide your processes and a detailed description of your data.

Best regards,

Hi Marius,
Thanks for the reply, It's working now Smiley

Now I am struggling to interpret the results of the output after applying Association rules, the results are as below
List of ID's and columns representing existing product names with values as true/ false (if product is subscribed/not subscribed)
and few new columns as "Confidence(prod1)", "Confidence(prod2)" etc. having values 1/0.
I assume that these column may be recommended products, but a close inspection shows some products in recommended list are already subscribed

Any thoughts on this
Regards
Deepak

I assume that these column may be recommended products, but a close inspection shows some products in recommended list are already subscribed

Indeed the 0/1 indicates recommendations. In fact some of the products can already be subscribed. The reasoning is the following. Suppose the following rule:
[A,C] => B

And the user has the products [A, B, C]. Then the rule matches, and B is suggested.
I will add an internal feature request to check for these duplicates, though.

Best regards,
Marius
